CR(M)250AR SUPERMOTO BUILD

[Jeram]

I just got about 50 individual honda parts in the post, that should be all the suspension linkage bits and PV/cylinder bits

[Jeram]

all my cr250r parts from the USA turned up! yay!

you know youve ordered alot of parts when your coffee table is stacked up three deep plus more waiting at the post office for monday!

[Jeram]

The Flywheel mods are done

should now be compatible with the race ignition

[Jeram]

now begins the painfull process of pulling apart the wiring loom and hooking up the ECU...

after slicing it open and marking all the wires that I need, Its not looking so daunting anymore... will take a couple nights and a few beers to get it right though..

[Jeram]

its just nice when things fit properly...

this is why I chose these particular wheels...



chain lines up perfectly,



wheel is centered



one of the CRM spacers fits perfectly into my cushdrive bearing to make the perfect width spacer to offset the sprocket from the swingarm.



This also is the perfect legnth as the rear brake bracket now acts as the perfect spacer on the other side, I just need to file the edges down a tad to make sure the bracket only contacts the inner bearing not the outer.



all I need to do now is wait for the cush rubbers to turn up in the post, then get a disc and some 20mm ID wheel bearings so suit the CRM axle.

couldnt be any easier than this!


as for the front, it all seems to fit nicely with the stock bearings, Iv ordered some new ones and need to swap them in,
but I need to get my triple clamp machined out to fit the forks before I worry about the wheels, then its just a matter of centring the wheel and making spacers and off seting the calliper if needed.

[Jeram]

my mate john and I made all the spacers and bushes today, plus bored out the triple clamps and made some brake brackets for the KTMITO380

[Jeram]

not far to go now

[Jeram]

I know I was told to run the stock airbox, but I found that will the new carb, the new manifold, larger shock spring...

it all just became a little bit too hard...


so I just picked up this brand new air filter off ebay for $5 !!!

I honestly think that the inside of this car air filter is the same size as the stock airbox haha. so I think that If I semi enclose it, it should work perfecty

[Jeram]

Finally sold my zx12r after 9 nightmare-ish months of restoration...

so I went on a shopping spree to get all the parts that I need to finish the bike off
I was suprised tho, I couldnt find much stuff that I needed/wanted to buy... that must mean that shes almost finished haha




RM250 OEM ingnition pickup (twin wire for the race ignition)



CRF450 rear master cylinder (built in reservoir!)



CR250 2007 stock OEM head (the Phathead racing head isnt going to work on my bike)

[Jeram]

My graphics turned up in the post today and went straight on the bike

[Jeram]

charging system works, and the ignition pickups are pulsing perfectly!

just need to head down to the supermarket tonight to grab 2x 6V torch batteries so that I can turn the ignition on
(I cant turn it over fast enough by hand to produce 12 volts and the drill attachment hasnt turned up in the post yet.)

then I can test for spark and test the servo motor.

pretty happy so far because it works first try! (after 2T institute made some corrects or me haha)

[Jeram]

electronics are all working perfectly now...
got spark, tps, servo and all the switches are responding.

just need to slap the top end on, get the rear brake set up and then Its dyno time.

Was bored this weekend, so I ripped the purple seat off and replaced with this

[Jeram]

shes finally a proper roller



machined disc, offset calliper, modified caliper bracket



strut while shock is rebuilt


modified the frame slightly so we could use the CRF450 master cylinder as its got the built is res'



brakes work brilliantly, and the bike honestly feels like it weighs around the 100kg mark

[Jeram]

The stars have aligned, a new class has been created that the CRM fits into.

Supermoto S4, which is an unlimited supermoto class, hosted by Preston MC.

First round is at broadford early next year. Hope I can have the bike properly sorted by then

The SM boys are hopeing I can make it as we really need healthy numbers to keep the SM classes alive. So far 12 people have put their hands up to enter which is great.
