The weaker spring shows itself when you get the tuning just right and using big cams. Will hold the slide open for a second at WOT when you try shutdown. A bit disconcerting at the end of straights...

Did that price you paid include the shock and swinger? PM me the dealer if you wouldn't mind...

hey sorry for the delay... the needles are swapable for a range of keihan carbs. They have three letter codes stamped on the side for taper and diametre measurments. I think the stock ones are JJH. There are needle guides online somewhere...I have used a couple of sizes up and combined with...

did you get the frame yet?

may be cheaper to ship a couple together...wink wink nudge nudge

I have converted a few cromoly cradle frames for others to take the 70 plastics, seat and tank but they were not ideal for the job. I am wanting one of those ssr frames ASAP too.

way to go. where did you get your hands on one? They are sposed to have fixed the rake problem with the billetware frames. I want one to look at and save me making my own frames.

would you go an put your 80 2 banger plastics on yer 250 to find a new look... haha I agree the crf plastics are better looking but all they had to do was the 70 plastics and seat/tank combo instead of the 50's to upgrade from a 10" bike. Its a simple case of ripping the consumer off for the...

not only that very good purpose of plastics, I can't believe all the doods around the world, especially here in Oz, that don't realise how spastic a 12" x 14" wheeled bike is with 50 plastics. The problem started when some idiot decided to put larger wheels on a 50 and sell to the masses that...

hey all, 26mm oko is best budget carb for the 140 I have found. You can help the snap off 1/4 throttle by fitting a better tapered needle. This is how you feed a bit more juice low down without upsetting the main jetting. I may have said before, but I also use the 26 oko for specially built...

yeah it has been a while. The site changes reactivated my subscriptions and threads have been hitting my inbox again.

yes those were the days...

For the 26 oko heres what I do. Pull the entire carb apart. Very simple. Including the jet housing. Just two screws and it lifts out to reveal the drillings underneath. Basically I ensure the drillings are accurate and clear of castings, sharp internal bends are cleaned up. Also the exit...

Your cams generally need to be made bigger so they build your stock cam up by hardwelding, then regrind to the profile of a master they have. Cam grinding outfits are mostly just copiers. They get a cam they want to copy and put in their grinder. The machine follows the profile very slowly...

Run a straight edge of some sort across the rear sprocket to the front sprocket. A large builders square is pretty good for this or one of those 1 metre steel rulers. Sounds like you may have mixed the spacers up on reassembly...
