Thank you It has been a labor of love so far, I have had to fabricate a new gear foot selector as the other one was rather loose but couldnt be tightened as the bar was anchor bolt was bent but I couldn't just use a replacement bolt as it would bind up when tightened so I made up a couple of neoprene washers to stop it from binding, then due to the short in the wiring from PO soldering in the original bulbs in order to get around using resistors when hooking up the new led's I hooked up resistors and replaced the LED's with new ones then hooked up the daytime riding lights, I was trying to wire in a relay wire system but after running all of the wires and stuff it wouldnt work and for the life of me could not figure it out even after going over the wiring time and time again untill I got to the stage where I thought bugger it so I just hooked it up via the switch going to a fuseable link to the battery and the lights to the switch and to an earth.....basic straight forward and I can run the lights with or without low and or high beam, had a few other bits and pieces that have had to be done but now all it needs is the rear tire changed with the new battlaxe I have for it as it gets a bit scary with the extremely bald rear on it
Good evening Kiffsta, all, and sundry. I own two of Hamamatsus finest creations; an '88 GSXR813 streetfighter, and a '90 Across. Also, another of Hamamatsus creations; a beat up '82 XJ750 donor. The Across is my daily commuter and has undertaken much refurbishment and improvement since buying it in December last year. I imagine I'm not the first to have performed a twin disc conversion, but I haven't seen any other examples yet. This site has helped immensely while working through servicing and problem solving on the berserk two-fifty. I have learned much in doing so and am happy to share my experiences and knowledge with anyone who needs it. Just remember, when in doubt, gas it out!!
I just need to machine the spacer down 13mm and it's finished. Still safely rideable, but nowt perfect. I can tell you all about it later, but for now I have to throw some dinner together.
Thanks for the photo.....a first for me as I've never seen an Across with twin disc's up till now, well done Curious to know what you used for this conversion, you would also had to change the M/C as the previous one was for single disc. Thanks for sharing
Thanks for your interest you guys, there are heaps of cool things the X913 could have but the factory (moreso the accountants) ruled out. The early model Across was built with a R/H disc but the L/H hub still has the rotor bolt threads machined in so the plastic cover was removed from it and a set of Metal Gear alloy centres installed. Kudos to anyone who may know which bike exited the factory with twin rotors. The L/H fork is off a later model Across and accommodates the LH caliper. I thought it'd be that simple but there are further differences. Early model front axles have a single plane profile and are secured by a nut on the left side with a bush in the R/H fork end. Late model axles have a shoulder on the R/H end and screw directly into the L/H fork bottom. The R/H end is then pinched by the fork bottom (sans bush) once the axle is torqued. Speedo drive width is identical, but the R/H spacer requires only 15mm not the earlier models 28mm. I bought what I thought would work based on part number deduction but it has an odd over length section beyond the bearing cover flange. Bugger fiddling around with matching brake lines from the wrecker, I sourced a Venhill set and farted around with the varying thread pitches between the master cylinder and the calipers. The master is an RF900 5/8" bore which Suzuki also fitted to the Bandit alongside other models, but retains the Across' lever. The original 1/2" master wouldn't provide for the extra fluid volume required to shift the four pistons adequately, no matter how well they're bled. New OEM seals have been installed in the calipers and forks, new steering head bearings for the increased load, and organic pads. I'm running the recommended 10W fork oil but would probably experiment with a 10/15W mix and some new springs. The master cylinder is serviceable but will be refurbished as a rite of passage. While this new front end may not be completely necessary, I like a heavy set of anchors and it was a relatively cheap and easy enhancement that looks the grouse.
