    I'm going to have to take pictures of my other smokers, but this ones a runner. I'm 23, and I also have a 1979 RM125 and a 1976 GT550 that I am restoring. Just picked up this 1971 TS185 a few weeks ago. It ran when my brother and I got it, but poorly. I pulled the carb to rebuild it, but it was un-fixable. The previous owner said it was taken to a shop to have the carb tuned by a pro, LOL. :roflThe needle jet had no shape, it was just straight like a peice of steel just put in there, the slide was tight as fuck, and had been forced in there incorrecty, it had a quarter jamed in there to hold the cable, and the adjustment screws were cranked in as tight as possible, the idle included. I put the settings back to stock and it ran like garbage, rich as hell. After all of those problems we said fuck it, and ordered a chinesse carb for her. Bolted it on, and it started first kick. Fucking right!:wink: My brother and I took her for a ride yesturday and it worked great, we rode for an hour or so untill the jacked up chain adjusters let the chain get real loose. Pretty good for $300 I think.

    What can you tell us about the headlights? Also a candidate for posting in 'the cheap bike challenge' thread.

    After I rebuild the 250 motor, I'm going to drop it in a 2000 KX250 frame. It'll be cool, I promise.

    Hi all. Long time lurker first time poster here. Some of you may know me from the kaw boards. There sure are some nice bikes in all those pages. Anyways I thought I'd say 'hey' and show my bikes.

    75 Kaw S3A, rebuilt engine, ported, stage 2 reeds, Denco repops, ram air induction. I dont know how much hp its got but it isnt stock by any means. Ive had this bike for 25 years.

    [​IMG]

    77 CT125. The 'farm bike' from what Ive seen about it. Only imported one year to the US. Tank is incorrect, but as far as I can tell, 95% is there and in great shape. Only has 3k on it. Runs like a swiss watch. Thinking of selling this little critter though. It sits alot.

    [​IMG]

    71 RT1B. Needs a repaint and new 'undented' tank. Threw a rod in it last fall so it's on the slate for a rebuilt crank.

    Dude! That S3 is KILLER! Absolutely gorgeous. I've always had a soft spot for this one, but a '79 RD400 got in the way of me ever buying an S3.

    It's been moodified a bit. :D

    http://www.3cyl.com/mraxl/aylor/reeds/reeds.htm

    Cylinders were decked (a shade more than I should have :fpalm and that was my mistake), intakes had to be shaved for 30mm carbs, been bored .20 over, Paul Gast did that work, I added new boost ports, reed kit, and added 30mm mikunis help it breath. As you can see, there's a big difference in size. :huh

    Build thread is over here if you want to see. It was alot of work but I like it. I've had this bike for a long time and it's almost like family. Lots of memories and it's twice the bike it ever was. :thumb

    The Find!: GasGas 1995 JT35 posted on CL and quickly purchased it:

    [​IMG]

    Due Diligence:
    The previous owner purchased it in San Jose in 2011 and did not do any maintenance, or ride it much. He bought it from someone who could not start the high-compression motor.

    Developed by 7-time World Champion Jordi Tarres (hence the JT model) for GasGas to compete in the World Trials Championship (WTC), this model won the WTC 3 consecutive years from 1993-1995.

    This is not a beginners bike! Quite scary!

    I contacted Jon Stoodley http://www.gasgas.com/tech.htm , one of the key figures in preserving Trials scene here in the USA. Jon told me that the bike was originally owned by Steve Darrow, a National ranked US Observed Trials Championship competitor. Jon had made some head modification on this bike to make it easier to start. This bike is a 'big-bore 2-stroke beast: capable of 6th gear wheelies. The 327cc engine was the most powerful trial motorcycle produced by any manufacturer until the 1996-1997 338cc JTR370..

    The engine design is considered to be bullet proof. Used in GasGas trials models till 2003, it is also used in the 1995 to the current generation of GasGas EnduroCross bikes which have roots in the Cagiva/Husqvarna WR chassis design. The EnduroCross 250/300 uses different transmission ratios, cylinder, and incorporates a exhaust powervalve. Trials manufacturers no longer build these big bore bikes (current models are under 300 cc).

    After a few hours inspection, and routine maintenance, everything works!

    Due to the heavy clutch use on a trials bike, we run Dexron III ATF fluid in this transmission (or 5W30 Dino oil) and never sythetic oil. The transmission 1st-4th gear are suited for trials, with 5th & 6th set up for trail riding.

    The Paioli fork design which was used by GasGas until 2001 (Current GasGas Pro uses Marzocchi), Sherco to 2009, and Beta to 2010. The Paioli RSD fork has only one spring held in the Left fork with 280cc of 5W fork oil. The dampening cartridge is held in the opposite (Right) fork with 330cc of 7.5W fork oil. Bleeding the AJP clutch (mineral oil) and the rear brake (DOT 4) is interesting as you push the fluid up though the nipple towards the master cylinder: as opposed to filling the upper cylinder and letting the fluid drain down. The bike has all the components of the GasGas Factory WTC bikes: Dellorto PHBH26CS replaced with Keihin PWK28 (yes a 28mm!); Kokusan ignition; Boyesen reed valves. You'll notice that a trials 2-stroke does not have an expansion chamber (note the exhaust pipe).

    These models are wired for lighting, and were street legal in Europe. I will probably get a CA license plate for this one in the near future.

    Nut and Bolt check complete, lubed, and fresh fluids. Replaced fork oil. Tyre pressure set: 7 psi Front/3.5 psi Rear. Fresh 80:1 Pre-mix.Taking her out today to bash some rocks and logs!

    Here's the Jordi Tarres video:<iframe src="http://www.youtube.com/embed/bi6cJaXnQTE" allowfullscreen="" frameborder="0" height="315" width="420"></iframe>

    First Ride Report: The JT35 definitely feels heavier at around 170 lbs. In comparison the trials bikes over the past decade are sub 150 lbs. The geometry is fine and comparable to more modern bikes, but some bikes have even tighter steering lock. I need to get fresh Michelin X11 and adjust the clutch engagement: I kept on pushing my front in limited traction turns - and I should really lean the bike more and turn the bars less (oxymoron when you are practising full lock turns.)

    It feels very planted, and compared to my daughter's GasGas TXT Pro 200, it much more suited for trail riding. Gobs of torque which let's you power through anything, even more so than my GasGas EC300. But relatively a challenge to kickstart with the high compression and low exhaust port. With the proper technique I can kickstart in the first or second kick. Good fuel mileage - we rode 4-hrs. yesterday without refueling.

    I highly recommend trials as the foundation for all riders. It will make you a much more controlled and proficient rider.

    Watching those guys do that trial stuff running up and over the biggest obstacles with that much balance is amazing. It really takes some skill.

    Nice machine. As light as those bikes look, they have to be a blast to ride.:thumbup
