1989 Honda CR 250 rebuild

Bike was listed as “locked up”, but very low hr bike. Pretty much everything was original except FMF pipe and silencer and bike was stored inside.

The last time it was ridden it sucked in dirt. Crank was sent to Ken Oconner for rebuild.

In seizure cylinder wasn’t damaged but plating was flaking pretty bad. Cylinder with Pro X cast piston was sent to Powersealusa.

The chassis on the bike was clean and original. Just a good cleaning and regreasing. Shock bumper was missing, so it was dropped off for a rebuild.

Carb had 58 pilot and 178 main. Previous owner also had a reed spacer on the intake with an FMF gnarley pipe.

For Racetech fork springs owner had to make make a pvc spacer as the new springs are 40mm shorter than originals, stock springs had a lot of preload on them, owner went with a lot less at the RaceTech recommended 4mm preload.

Parts

  • Pro X rod kit
  • replaced all bearings and seals
  • new seat
  • Boyesen reeds
  • yzf pegs
  • SFF forks
  • Excel rims
  • PC raw pipe
  • OEM clutch cable and intake bolts
  • Works Connection frame guards
  • Racetech fork springs

2006 Yamaha YZ250 (Tom Morgan YZ315 stroker)

https://www.vitalmx.com/forums/Bike-Builds,46/2006-YZ250-TMR-YZ295,1345261

Part list:

  • DEP works pipe, R304 shorty silencer,
  • 2008 CRF450R front brakes,
  • Vforce 3 reeds, new plastics,
  • chain and sprockets,
  • brand new 2018 YZ250 wheels,
  • Tusk 270mm adapter to get 2008 CRF450 calipers,
  • Red Label is making the graphics,
  • GUTS seat,
  • Tom Morgan 295cc ported, milled head,
  • Magura Clutch,
  • R-tech kit, blue Luxon clamps, and 18 YZ450F front plate and fender,
  • R-tech tank,
  • Acerbis blue frame guards,

Owner found one in Yamaha for less then $2,000 and it was a bit of a mess. Front brakes barely did anything, didn’t run right, chain was shot… just a mess.

Frame was really bad shape, slow spinning wire brush on the end of a drill was used, a Dremel and some scotch brite pads.

Had to order the Tusk 270mm adapter to get the 2008 CRF450 calipers mounted. Brakes work fantastic now that it’s bled with new system!

After Magura Clutch install pull feels quite a bit better and reduced effort to pull.

After bottom end modification it will be 76mm stroker that will make YZ315. Tom Morgan was building it, along with flow benching reed cage and carb. He uses stock crank, balances it and uses OE Yamaha rod kit since OE is proven reliable.

A big bore pulls more air volume thru the intake tract and also requires a smaller throttle opening to create the same torque. This raises the vacuum in the carb which causes a larger pressure differential between the float bowl and the venture. This pulls more fuel thru the same size jet. The A/F ratio is the same but people mistakenly believe that it is leaner because of the smaller jets. The main change that you will make when increasing the engine displacement is in needle clip position and air screw setting. The main jet stays very close to the same as with a smaller bore

2005 Kawasaki KLX 300 supermoto

The KLX may not be the biggest, baddest, best sumo out there, but its sure a hell of a lot of fun.

There is room for improvement in some things, which were addressed with rebuild. First and foremost is the suspension (front sprung for 155lb rider, rear sprung for 180lb rider, im 195 w/o gear). New suspension will be sent off and resprung and set up for my weight and motarding along with the shock refresh.

Also owner disliked the sluggish way the vacuum operated stock carb supplies power so it was changed out for a Mikuni 36MM pumper carb. the Carb also complimented the 351cc big bore kit from Bill Blue.

  • Overall length – 2200mm
  • Overall width – 815mm
  • Overall height – 1205mm

This 1992 Kawasaki KX 500 was long coming project, because owner were looking for right motorcycle over year till this gem poped up. The goal was to update the brakes, wheels, suspension, clutch and all around fit and finish. And end result speak for it self.

Parts:

  • 2011 Kawasaki triple trees got the stem pressed out and the KX500 stem pressed in
  • changed fork stops
  • the Brembo brakes and wheels are off a 2013 KTM
  • EXCEL Rim
  • new impeller drive gear old on the end of the crank shaft was beat to death, mushroomed and had broken teeth
  • made bracket to utilize KX 450 sliders
  • custom made wheel spacers
  • 450 cover
  • rebuilt shock, race tech gold valve and bladder cap
  • hydraulic clutch
  • cerakoted engine – tungsten color
  • ported cylinder and cleaned up power valves
  • new clutch basket
  • seat cover from MotoSeat
  • resotred PRO Circuit pipe

Simple way to upgrade the clutch pull arm for a little more leverage. Take a yamaha 450 pull arm shaft and this billet arm thats a tad longer, weld the splines to your 500 arm.
