Try the EBC EPFA447HH pads instead of the HH version. 5 fold improvement over the already good Double H. Plus the last longer...

Listen up You need a tune to get the most out of these 390s. If you want the most out of your configuration, Chad is the man. Hey- stock, mild build, or "superbike", WellsTuned is your one stop shop. Yes I have driven the 8.5 hours one way for this man to put his hand on my motor. I'd do it...

Try the EBC EPFA HH. Excellent sintered performance. Much better than the old HH. Note on carbon pads, not sure on the little bikes if you can keep enough heat in them for best performance Sent from my iPhone using Tapatalk

I'd start with 10 wt. how much front rider sag do you have with the stock springs? Sent from my iPhone using Tapatalk

Ours did it while the RPMs were at 6k preparing to launch. I still can't believe Jeremy didn't lose it. When your guys reassemble be sure they give the the plain bearing in the clutch basket some extra clearance to the shaft. Your failure like ours was from not enough oil film. Sent from my...

I believe if you received an even slightly warped head from the factory and couple that with a low cost provider head gasket; chances are pretty good you could blow the head gasket.

Some of you may know that we (G-Baby Racing) had a catastrophic clutch basket failure on our bike. The result was the engine primary was locked to the transmission main shaft. (you couldn't release the clutch). It happened while one of our riders was preparing to practice the launch. Made a...

Actually, an ECU can just quit. Especially early in it's life cycle.

Bobby PM me and I'll be glad to give you a great Stage 1, Stage 2 build plan to consider. This is from our last years sprint and endurance program. Oh and welcome aboard!

SBS Superbike Sintered work very well on our Endurance prepped RC. Also available via Vortex Racing.

I was told today about the same OTD as the KTM. But a better bike comparison would maybe be the CBR300?

Fiberworks from Japan on my bike ($219 shipped to KS). I guess you'd call this a modified 5-F-STR ? Sorry about the numbers tape in a hurry during an endurance event when numbers came off.... .

February 2016 RRW interview If you all are interested, I'm putting together my thoughts and experiences with this bike with a year of nationally racing it in endurance and sprints. My reasons and thoughts for the build in this article, where it is now, and where it's going.

This is one sticky but very abrasive track. Don't go there with marginal tires. Tire wear is extreme - even on a 40HP M/C

I guess if you weigh like 100 lbs you could get the available from WP cup bike springs to work optimally for you in a race environment. All the MotoAmerica cup riders I know are not happy with the limited WP supplied spring options available in 2015.

Using a Baxely up front instead of the side stand with a hydraulic jack is a different story. Actually that's a pretty dang good idea.

Hmmm - no I'll use jack stands thank you.

If you are going to go from Ethyl Glycol to Poly Glycol (change to engine ice for example) you must fully flush it with water. The Poly and Ethyl are not compatible.

Actually it does work. I used two adjustable craftsman jack stands and positioned them under the mounts for the folding rider pegs. It was very solid and kept the bike fully stable for the entire shock replacement. Sorry I don't have photos - it was done back in April before I installed Tyga...
