HOLY stool!!!!! :awesome: :wth: :toot: :haw: :eng101:


I bought the kit from Race Concepts and it is pure joy. The biggest difference is it keeps pulling from 30-60mph. I have done no other performance mods. I may add a little taller gearing to get me over 60mph in the future. If you are on the fence on whether to upgrade, BUY IT!

I sent you a personal email asking this question, but I am not sure it went through, so I will ask, again, here.

So what did this setup do to your performance below 30 MPH? Is your performance below 30 MPH better/worse/unchanged?

1500 rpm spring light rollers, 8g and 9 g rollers, will make 1 to 30 mph feel like a real motorcycle out of the pocket. Is how the performance for a 155 bbk feels at 1 to 30 mph. keep stock final drive gearing in there and you will pull the front off the ground if it has no stretch. ( depending upon your body weight )

Yep performance is also better at low speeds. It will barely pull the front wheel off the ground on take off (I weight 200lbs). It's just the increased performance is more noticeable after 30 mph compared to stock.

If you want it to really pull consider a TST 2 stage variator with 9/11g weights from RC.

thanks for the support!

1st thing you have to get is a aftermarket clutch and clutch bell. with more power the stock one slips. this alone will add performance and increase top speed. eliminate slip and all the power goes to the rear tires. PG clutch and bell combo is a solid choice since it's a heavy unit so it's smooth and built to last forever (carbide steel clutch bell) had a customer do a burn out and wasted the clutch pads, then melted the aluminuim clutch onto the PG clutch bell. normally any clutch bell u toss it away but PG is carbide steel it survived. cleaned it up and installed a new clutch.

2nd item be the rc cvt kit with the TST variator, changes the way it shifts and adds acceleration. large diameter variator increases top speed.

if you plan to ride pass 65mph often then i would also get the aluminium rear torque driver. does not have that fat weld spot found in steel versions. so does not flip the belt or chew it up at high speeds.
