The EVIL TWIN

[Graham]

Well Im ready to give her another go this year, shes a 1977 KZ400,has a two into one,ported and polished,race cam, raised comp,twin pumper carbs,RM250b shocks, IT175 front end,3x inches added to cradle to lower the engine to get a better centre of gravity, last year she had about 4x outings each time teething problems arose.
It gets up a goes quite hard and has the best sound when in full flight.

Still its going to be a learning curve as now all I have to do is workout how to wrestle 138kgs of bike around a MX track

One question. Why?

[Graham]

Because

good on ya mate  if those bloody Aprilia SVXs can give them a good go off road, then no reason not to apply that twin cylinder advantage to VMX. Hmmm i know where is an old YZ frame and RD 400 engine.

[magoo]

Fair enough

[Husky500evo]

Somebody has already done the YZ/RD Hybrid thing . I don't know if it would be fun to ride , cause I wouldn't think the RD motor would have a lot of bottom-end power .

[Marc.com]

wow bet that really improved the value of the YZ   

[vmxken]

Love it or hate it, that Yamaha is in Issue 37 of VMX.  The bike was constructed in memory of a bike that Kelvin Franks built in the '70s, which was raced by, among others, Mike 'Too Tall' Bell.

......now, back to the Kawasaki!

Hell Ken..... really looking forward to issue 37 now, god bless the special builders particularly Kelvin Franks who I think never got the recognition that was coming to him, if only he had built a production run of fast XR500s.

Have seen photos of that german guys KZ750 twin he raced it in europe in enduros, the story goes he couldnt get a ride with BMW so he got a KZ 750 and turned it it an enduro blke went out a cleaned up the class, next year BMW wanted him on there team.
Have also seen his KLX250 with KZ440 twin in it. He still competes in vindros on the kz750.

[Graham]
