Wrenching (Moderator: Woofentino Pugrossi)

My left hand operated rear brake ... anybody using a left hand operated rear brake setup ? ....been using my design for years ( US Patent 7621380 )...pic is from the 2020 ROC ...#12 race on Sunday - Classic Superbike Unlimited...track had standing puddles through the infield...rear brake really helped to slow ... absolute vertical while modulating the rear brake and feeding in front brake...worked well...if I had rains instead of Pirelli slicks might have worked a lot better lol...

Reputable PC5 tuners in Virginia? I have a PC5 on an newly track converted 07 RR that needs tuned in the Virginia area. I'm seeing https://www.rnrcycles.com but they are pretty up there in cost. I'm just looking for someone with a dyno shop that can do a better job than Auto Tune preferably around Richmond. Anyone come to mind?

Ohlins Front I purchased a race bike with an Ohlins FGK 1270 kit up front. I cant seem to find any info online about it. My questions are: How good are they, are they rebuilt the same as any other kit, and any other info you might have on them. Thanks!

06-07 R6 front sprocket nut solution I would use the stock retainer and fold it. Just chalk it up to being safe. I had a drive sprocket come loose and lock up at motor cross track. Put me on the ground hard could have been deadly. All because I didn't use lock tite. Do yourself a favor and be safe

2008+ Ninja 250 valves Look at the seat and the margin on the valve, if there's any irregularities or discoloration in those surfaces, lap them to make a good seal. As far as material and construction? 1 step above Briggs and Stratton.

Dunlop Tires for new racer at BHF Quote from: Racer420 on February 11, 2016, 10:15:29 AMI'm a new racer that has had good luck with Q3s on my GSXR-600 and Hayabusa.  I'm considering Dunlop 211  Gp-A's.  Any thoughts on hardness for front and year for a track like BHF?  Thanks for not going "Oh no.  Not a tire thread"I run medium compound for front and rear. I'd echo what Zaph said and run the GP-A Pro's. A few bucks more but you can flip the rear to get more use out of the tire.

Gen 2 SV650 mods Quote from: LWT Racer on February 13, 2016, 09:30:43 PMIn most cases I would say yes do this, but Zoran doesn't run them. Zoran can hook you up with Motion Pro Revolver cables for the DL Tbodies. Sam. Gotcha. I figured no matter what Zoran could point Guy in the right direction.

Suggestion: Ninja 300 race tires & more upgrades I've been getting race wins and championships for my racers with the Bridgestones. They also get tire certs. to help pay for them. I've had many people come from other brands and never look back. We have new tires 110, 140, 150 for 2016.

Gearing for Honda and Sv at PBIR? I don't run an SV or a CBR 600 but I have raced at PBIR. One up on the rear will be fine. That back straight is 0.6 miles in length and it is probably a second gear corner at roughly 50 mph. By the exit of that turn you are into third so plan accordingly.
