anyone doing any good upgrades for 2013?

Recommended Posts

At the end of last summer we bought a ktm 85 just to compare w/ are 150 , so far my 12yr old has only been riding the ktm and is very happy , just before we bought the 85 i bought a camarello piston and cam for the 150, and they are about to go in , so were going to do alot of back to back testing at the track , i just assembled some big wheels for the ktm also ,but he seems to like the 14/17 wheels for now so far he adapted to the 2t very well and seems faster,going to be a fun this spring at the races.

I'm starting with 2009 CRF150RB, bought used last year with the following parts:

PR2 head with BeCU seats, Ti valves and HD springs.

FMF PowerBomb/4.1 Ti exhaust system.

Works Connection skid plate.

CRF250R twin-piston front brake caliper.

Fastway pegs.

Oversized radiators.

Renthal 996 bars.

It also came with spare frame (CRF150R), short swingarm, small wheels w/new Dunlop rubber, stock radiators, and extra sprockets and chains.

I added a TT sidestand, RSW top clamps and risers, a Rekluse clutch and a Works Connection hour meter.

It's was a serious racer, run one year in both the R and RB classes. It has been extremely well maintained. The owner told me that the valves were checked after every other race and never required adjustment. The kid could ride, and used the powerband well without hanging on the rev limiter.

This year I'm going street-legal (to connect trails) and these are the mods I'm adding to turn it into a high-country trail bike:

Modifications to the engine to improve low-end torque and throttle response: Web-Cam #298 torque-grind cam, Cylinder Works 160cc barrel and piston and homemade flow splitter to go in the airbox (already on the garage shelf, waiting for the confluence of available time and good weather to install).

TT alternator/flywheel, w/Moose Racing headlight and Baja Designs LED taillight and a home-brew harness w/4-in-1 switch.

Bulletproof radiator guards and homebrew fan.

A 3" extension to the swingarm, and TM chain guide.

21" front wheel and 18" rear wheel, shod with DOT-legal MT-43s.

Heavier springs and suspension revalving.

Homebrew rearsets (1-2" lower and 2-2 1/2" back).

Handguards.

Clarke 1.7 gal tank.

Because it's so loud as it stands, I'll probably have to replace the Ti FMF exhaust with a FMF SS MegaBomb or used MRD torque pipe w/modified CRF250X muffler (the only one I've heard that's quiet enough for trail riding) before I go to the DMV for inspection.

Our bike is sitting waiting for warmer days,,,,,, spring thaw. CP piston, Crower cam, and Kibblewhite valve train. Needed to go up to a 45 pilot and going to try a smaller 138 main. So far the bike revs faster than with the stock parts (no load on bike). First race is March 3 and hopefully will be all dialed in by then.

I personally wouldn't get the new head if you are looking for all out power.

just an update the valve springs i ordered , stayed on back order , so I ordered a pc kit , its all put together , just have to put the head back on and shim it , i think im going to start with the stock cam do some base line tests then drop in the crower can , and decide what were going to race with , the cp piston fit like a glove , all in spec whether is nice enough to do some good back to back , i;ll be running 110 sunoco /premium gas 50/50 , son took a bad practice crash this weekend the worst since he has been riding,he cart wheeled serveral times on the ktm 85 we have , luckly he walked away unhurt , just proved to me , its a must to wear proper protection , bumped his head real good so i went out and bought him a top of the line carbon fiber helmet

just had a soar kneck ,he is very good about wearing protection kneck brace , elbow guards , best boots , chest protector etc I truly belive this saved him from serious injury

How did the race go? What's your take on the engine mods? Did the jetting changes work out?

Glad your son's OK. Hope the KTM fared as well. Looking forward to your feedback on the cams.

After dropping the bike on a down hill trying to pass lappers, then power slide out of a turn tossing him on the trail, he placed 5th. I will say this with the valve train there is no valve float at all. My son passed a rider going up hill in 4 and couldn't shift (so he said) and the motor just wrapped away not losing any power. How much did the motor work help??? could tell because the track was thawing from the morning of 20*f. I ended up going for this race to 45 pilot, 48 leak and 140 main. Ran good but with the cold the motor still needed a bit more fuel on low end to keep the Rekluse from occasional stall. The motor has a bit more valve noise compared to stock. Had to run 92 pump gas so it might run better with 50/50 mix. This weekend he will get a complete suspension revalved for the woods.

I don't ride below 50 but he rides all the time. My son crashes when he gets tired by being lazy. First big crash put him out for 14 hrs and cracked a brand new helmet. Two weeks later he thought why put weight on the front then to the rear, just split the difference and stay mid seat. Washed out in the corner and got ran over by the bike he just flew by. His neck brace took the hit but still walked away whit a poped out shoulder. Super mini class is very tough and the speeds are right there with 125-250 school boy.
