as i'd done the CDI mod to my gt250r a few days ago and already have a screaming demon exhaust on it, today i cut open the intake hole on the stock air filter to increase the air intake and moved the little circlip on the carb jet needles to make up for the lean-ness. sounds much better now, gonna see how the power is when i ride to work later today
Sold the 1969 Duallie on Bumtree for a grand, Saw my Barn find z50J1 for the first time and pushed out into the sun (hasn't seen daylight since 1984) Strapped her back in and came home from Perth.... this is true love. Of all my bikes the R3 and the Z50 take pride of place, my collection is complete
The Z 50 brings back found memories as I bought one brand new for my son many moons ago. It was registered and so much fun and so easy to park......anywhere.
Yeah 'Its a Honda' it'll run. But Im dreaming of Daytona Anima 190 4v, 10's with low profile tubeless, subtle longer swingarm shocks and forks, but keep the rest stock and unmunted factory parts. 2.5hp 49cc 3 speed auto wont cut it as a daily rider. I never believe in wasting money on mods for bikes, especially roadies and 250's, but the z50 is more of a novelty if that makes sense. Prices aare through the roof at $4500-$10,000 for J1's so have to be sensible in the planning.
Made a leak down tester to see if the crank seals on my NSR250 engine are in need of replacing (very thankful my uncle hoards plumbing supplies saving me $100 for a ready-made tester!). So to save my back I tested it out on another MC21 engine I had which is on a convenient stand on the bench. And the leakdown tester works but this engine leaks between the rubber intake manifold and the reed cage... where there isn't a gasket. So I think the rubber must have gone hard. It's hard to find those rubber intakes in new condition but they're out there. I also have a spare used one in good condition. I've heard of tricks to make the rubber soft again, specifically soaking in wintergreen oil. But apparently it smells quite strong. Any tips and tricks you guys might have?
What I've read on oil of wintergreen suggest you mix it with isopropyl alcohol, soak your item in a sealed container for 3-4 days, and then let it dry for a week. Very time consuming.
There as many different 'secret' mixtures for this as there are bike restorers. The only one I have used was 50% ATF and thinners. Was unimpressed with results. I usually just heat the bits with a hot air gun until soft and squash into shape and hold while cooling. Why not use a gasket under the intake rubber to make a seal?
I was considering it. I think I have some gasket paper lying around to try and make one. I could also just use regular gasket maker. I could probably just use another gasket on the other side of the reed cage as well. They're only a few bucks. Oh, today I also mucked around with this KX125 exhaust I'm trying to fit to a CR125. It's not nearly as easy as I first thought but should be worth it.
Rode the fizzers with @Murdo and a few more VJMC blokes out to Kootingal, the scenic route. For the locals, we went from Wallamore Rd, Appleby Ln, Davidsons Ln, Upper Moore Creek Rd, Moonbi Gap Rd... Known as "around the block"
Lucky bastards I reckon, I've been sanding fairings all day, Got a postie bike in a thousand bits in the garage undergoing a makeover, supposed to be a simple front mudguard cutdown & paint but got a bit carried away. Had a ride on an MV F4 312 yesterday, beautiful thing & handled so nice, bags of power, now I want that H2 !
