    I feel like I haven't been doing any work on the bike for a bit. It's a good feeling. It still needs a fork seal, but I've been too busy preparing for my trip to Laguna Seca next week. Been building a winch into a tool box for ease of removal, that mounts to my motorcycle chocks in the truck. Don't wanna slab 1k miles on the ZXR at 12000 rpm, after all. Between that project, and the XS650, all I've done is ride... and the more I ride, the better it runs.

    Whatever gunk I failed to clean out of the carbs seems to have finally dissolved, it always sounded fine until i took it for a long bomb through the valley a couple weeks ago, and realized how much healthier it sounded afterwards! Never doubt the ol' Italian tune up!

    I hadn't ridden one of my VT250F's for a while as the last ride was problematic in that the bike wasn't running too well. Last week I pulled it out to have a closer look. Cleaned carbs and made sure everything was where it was meant to be...oil, fuel, fluids etc. On startup I noticed a ticking coming from the rear cylinder. Not up high or down low and not your usual valve clearances or blown big end. It sounded like a cam tick, so I pulled the engine out for a good look and to do the valves etc. I warmed the bike up for 5 or so minutes to get the oil hot and then dumped it and then the water before pulling the engine out.

    I've never had this engine apart, so I went with the simple stuff first and pulled the sump off to check the oil pickup and pressure relief valve. As I was doing so I heard the sort of noise you really don't want to hear...something was rolling around in there and making a metallic clink as I moved the engine around. Oddly, for me, I calmly removed the sump to see what was going on in there. I'm constantly amazed by how much abuse an engine can sometimes be given and still (basically) run!

    A few large bits of metal fell out that I didn't recognise and so began my adventure.

    Lets fast forward to the end...

    Tensioner 3.jpg

    The Parts Manual identifies part number 14542-KE8-000 as a cam chain tensioner guide. Google it and you get an image of 14540-KE8-000 (part number 11 in the diagram). Anyhoot, Once I had extracted all the damaged/broken pieces of this part, I was left with no choice but to split the cases to get to the anchor point and remove the bit that was still attached to the case. Here's a good one next to the bits that fell out. The arrows show the nuts on the main part of the guide.

    Tensioner 1.jpg

    Here's where this little sucker lives normally and where it is bolted to the bottom case. It's an odd device as it seems quite brittle and holds a tensioner in place for both the rear and the front cylinder. There are little hard rubber grommets pressed into each holder, so I'm guessing a wise person with good skills and tools could make one of these out of something a little stronger and maybe even as one piece instead of the welded together rubbish that comes standard from Honda. The fact I couldn't find a replacement anywhere means I'll probably have to tap a mate on the shoulder and see what can be made to do the job.

    Tensioner 2.jpg

    And, in conclusion, it would appear that the ticking noise was the rear cylinder cam chain wildly flaying around without a tensioner on one side. The front cylinder had both tensioners as the bits that broke off the part were only for holding one of the rear tensioners. Have a good weekend all.

    (not sure if this is a current thread) I put some new shoes on my mc19, Pirelli sport demons, and I might even do the valve clearances on Monday :)

    Well, today I was hoping to finish the DR350 and start on the WR250F. That was ambitious. This is as far as I got by 2:30am:

    Some bits have been a little fiddly, like reviving the clutch cable and trying to work out the wiring/cable routing. Other jobs were involved, like cleaning the swingarm and linkage bearings. Noticing some issues, like no neutral position sender. But you can't win them all.

    Today rode my bike! Just for fun, by myself. I don't usually go out much, just when I have somewhere to go I might choose to ride, but can't usually justify leisure riding. Not that ^ DR350, but a different DR350. Rode passed a place when I was riding with a friend a few years ago and he had a head-on collision with another motorbike (both dirt bikes on a dirt road, but the other bike wasn't registered) - no such dramas this time. Might need to tune the suspension, it was a bit harsh.

    Since my workshop is maxed out now that I'm wrecking the CRF450, progress is slow once I have it all organised. Forging ahead with finishing the CR250 though. Fitted the CRF450 fork - It needs a new lower bearing but for now it's just bolts up to look good.

    Also going to salvage the seat cover from the 450. And the rear wheel fits too! I got a set of graphics for the 450 so I'll be cutting them to fit the CR250 plastics. It'll do for now. The brake line is really taught too... gotta fix that.

    <Warning: long story)
    I rode my DR350 on Saturday. But here's where I went wrong:
    - I offered to ride sweep at an enduro round, which I've never been in an enduro before, nor been sweep.
    - I rode to the event (which also means I needed to ride it home, unbroken and me unbroken), an hour and half each way on the highway on knobbies.
    - I didn't have bark-busters, which means my knuckles copped it, but I could hit a front brake on a tree/sapling and knock my hand to twist the throttle on (front wheel stopping and turning while the back wheel is trying to speed up is a bad combination)
    - On the sighting lap, after a bunch of sweepers and a rider missed the first turn and got lost, I didn't get 500m into the course when my front tyre went flat. So returned to the start to fix the tyre, except I had nothing to fix it with. So I borrowed tools, got offered a tube, and an air compressor and fixed it. But to avoid pinching the tube (I still had to ride home) I put 25+psi in the front tyre - terrible understeer on the tough and tight course with lots of rocks and loose stuff.
    - It seems the suspension is too firm or air in the forks or too heavy of oil in the forks, whatever it was, it was not right.
    I can't remember if I did 3 or 4 laps, but the course had deteriorated, I had crashed more times than anyone else (my lower body hurts from crashes, my upper hurts from picking the bike up) and I had to ride home. Leaving early early was a smart move for another reason: it was full moon and the furry grasshoppers would be out - there were plenty of dead roos on the road.

    When I got home, my head was full of noise from the wind noise and such, I couldn't hear properly, and then I discovered that I lost my wallet... Fortunately a cyclist spotted it and handed it in on Sunday. My bike needs a clean, still, I've left it on the lawn right where I pulled up on Saturday night I suppose I should look after it, it did take all that abuse and only broke one indicator.
    Those enduro riders are crazy!

    IMG_7507.JPG IMG_7518.JPG Well today all I did was drive, but I spent the last few days in California with the ZXR. Went to Laguna Seca to watch WSBK, and took the ZXR since the Duc wasn't running. A few lessons came out of it for sure, but it ran up and down the coast for days, hammered its way through downtown SF pissing people off at 18k RPM, visited Cars and Coffee in Santa Cruz... the list went on and on and on!

    I just got home tonight. Tomorrow I leave for Portland, Oregon. (Yes, I went through there today and have to go back now...) what an absolute riot of a trip, and shockingly a couple people even knew what I was riding and what made it cool. I didn't think they were gonna let my bug-encrusted bike into CnC, but when one dude tried to kick me to overflow, another one waved me in, and there was a dude standing around when I parked who knew what was up... craziness.

    I brought the gospel of RPM to California and gave many people and many tunnels all the revs I could find... and it was good!

    IMG_7858.JPG Today I rode from what I thought was the middle of nowhere to a spot that turned out to be equidistant from anywhere.... but I did it with a friend of nearly 20 years who I somehow convinced to get his endorsement nearly half a decade ago and never rode anywhere with 'cause he lived 200 miles away! Fixed that tonight!

    Started the fork seal replacement on the Honda. Of course one bolt had to be seized didn't it, the bolt at the bottom! Never mind, had to get serious now, and after trying in vain to jolt it into moving I drilled a pilot hole, and then a 5mm for an easy-out. I didn't know how far to drill, or if the bolt went into a blind hole so I was careful. It was seized good. The old bolt is stuffed, but I got good 8mm socket head bolts from the local industrial supply shop for 50 cents each. By the way, the same bolt on the other fork leg all but fell out when I got to it :) Work continues tomorrow...........
