Sexy Bike thread continuation - TM or RN ???

[JohnnyO]

The Kiwi's are keeping quiet, I reckon it's another "Fine Cotton afair"....I just looked at Terry Goods site and theres too many iregularities (shit thats a big word).....I think maRc may be able to shed some light on this.

Yeah Davey it's nothing like the real deal.. DeCosters '73 RN

Pipe is most definantly a Jolly Moto (made in Italy) copy. Bitza, Works or converted TS who cares nice bike just the same.

, when I first saw it I thought it maybe was one of Mike Feltons jobbies......

No Mike builds them vastly cleaner than that, and doesn't raid the RMZ parts bin. Be interesting to know how the kickstart was fitted as shafts are hardened and would take some drilling and tapping unless it is imposter RM shaft.

[Marc.com]

BTW I think it is the real bitza deal, remember they were prototype racing so any combination of RH plus pre production or early production RM is possible. Remember Chad is effectively on a bike that is about 2 years into the future. Plus real race bikes tend to be rough as sacks..... can't forgive the kickstart though.

I know a guy that put a late model alloy kick starter on his TT500, but he told me it was hard to tap a thread in the shalf but can be done markfx
Its a shame that the photo of the suzuki above has a large gap between the seat and tank area

Thats how they where.

In regards to the shaft threading it is quite possible as Mick25 stated. As a temporary fix 15-20 years ago I did the same to the output shaft on my 400 to retain the sprocket. It works so well it's still there to this day and the replacement shaft is still on the shelf.

Alison, if you want the alloy kickstart it appears it would be available over the counter as it's a current RM-Z450 item. Only thing is it doesn't have a pinch clamp like the TM and uses a retaining bolt like the RN or RM N/T models so it'd require some work to fit. Not impossible but not a straight bolt up item sorry.

Think the kick start lever could be a 2000-04 CR 250

All shafts are case hardened, but underneath as soft as butter, a carbide drill eats through the hardening as does a properly sharpened masonary bit. Then followed with a carbide tap makes short work of drilling and tapping case hardened components.

That is the same gap as RH250 as we had original ex Miller RH74 sitting next to it to compare it to. You can see in the photo Daves RN is the same. Head and barrel are also NOS RH74, as are rubbers, bolts etc.... brake pedal and air box are made in NZ RH replicas. We have been mulling over the idea of a light RH74 frame kit in Cr Mo for TM 250/400 motors if there is enough interest.

Interestingly tank decals are in the correct position depending on whose bike it is..... story goes Suzuki moved them about to identify different team riders bikes in the pits.
