R1 bits morphed into an RD
Re: R1 bits morphed into an RD
Merci Ben!
Re: R1 bits morphed into an RD
Putting big forks on the LC requires frame gusseting. The swing arm bushings will also require attention. You know that LC hinge effect? Can you say, make it worse?!

Re: R1 bits morphed into an RD
That's a good point to consider, even though you are benefitting from reducing both sprung and unsprung weight with the new suspension, it is a few orders of magnitude stiffer than what it is replacing. It also has far more powerful brakes. This will amplify shortcomings in the frame that you may not notice with the stock suspension.
Re: R1 bits morphed into an RD
If you haven't already read Jeffs thread, it will show you the difficulty involved with R1 front and back bits.

Re: R1 bits morphed into an RD
Read Jeff's thread (thx Jeff) and note that he had to cut his RZ frame to allow for chain alignment. Not to crazy about cutting the RD frame as the motor and frame match. Suspect there is no way to engineer passed the chain issue. Considering sprocket(s) manipulation to alleviate the frame cut. Suspect all that machining will not eliminate all the chain rub/yaw could create metal fatigue al the way back to engine internals and/or snap the chain into a whip. Plain B - Yamagama this project but Ben is right - no Susie donor bikes about in this part of the hemisphere for that consideration. Perhaps create my own RD frame n' add on the R1 bits? - that type of R n' D means a second job, sleep deprivation, divorce (and this creation will probably be part of the settlement). Ahh, snookered perhaps. Forks easy-pezzy; swing arm not. Time to go for a walk or run and plus/minus this situation.
Re: R1 bits morphed into an RD
LC Cnd you really should reconsider my hybrid LC project. All the frame work etc has already been done .... at great expense I might add. The rolling chassis is there, it just need to be assembled and the details worked out.

R1 forks not easy-peezy. They are much farther apart than rd and closer to the frame and the result is hitting the tank at 1 inch turn to the left or right.LC Cnd wrote:Read Jeff's thread (thx Jeff) and note that he had to cut his RZ frame to allow for chain alignment.

I figure you can get a chain around a 140 tire(maybe a shaved 150) on a LC without widening the frame.(with offset sprockets) But the rear subframe and inner fender become an issue.
Another thing about the R1 swingarm: most 4 strokes have their front sprocket higher in the engine which keeps the chain off the swingarm by design. Not so with the RD/RZ
I am trying to steer you away from the R1 stuff because it just isnt worth the trouble for the cheap price. Find a deal on parts that will work.

Re: R1 bits morphed into an RD
Colin what do you suggest that is available in Canada - the dollar being what it is south of the 49th - that would that would come close to the profile in the attached picture for parts? Credit goes to Kar Lee for the concept design. I"m thinking R1 components (suspension/braking) create the majority of the bike and add marsbar colours. Headlight appears to be KTM. This RD concept looks to be a fun bike to build and ride. Suspect someone, perhaps in the UK, already has one rolling.

Re: R1 bits morphed into an RD
Impressive photo of a Serious amount of work (is it a Photoshop Build?)
Big Tires even US forks .. ALL this for a 37Hp (stock) Go Slooooo motor.
Priceless :-0
Your LC running yet?

Re: R1 bits morphed into an RD
Check out the lc crazy forum. Many bikes that look similar to the picture...or better.LC Cnd wrote:Colin what do you suggest that is available in Canada - the dollar being what it is south of the 49th - that would that would come close to the profile in the attached picture for parts?

I haven't built a lc custom...yet. But I plan to.

Re: R1 bits morphed into an RD
Did. Have yet to come across a thread that does not reference splitting the frame regarding R1 parts.
Re: R1 bits morphed into an RD
Well, 10 minutes ago I located a Gamma 250 fm a gent who wants to get rid of as it has been sitting abandoned in his place for 7 years not running. He knows what he's got - I'd didn't till I did some research. Apparently the bike's CDI is burnt out and he can't find a replacement. Lower part of the of the blue and white fairing is missing (thinks it an '87?) and so is the seat gone also. That said, how hard it it to convert the suspension/swing arm to an RD or the reversal put an RD motor (with loom) into a Gamma? Get the vibe RGV its preferable over the R1 - which is still available for free; the RGV isn't. Yes, the other bike has 27.5 pilots and 240 mains and idling well. Just can't test it due to monsoon season happening. Frustrating as I'm plated to the end of the month and all the sunny days I've been working. Next season it appears. In the mean time, like to get this build started and have 3 options. Today's odd offer came came outta left field - odd cause I wasn't looking for it. Time to contemplate.

Re: R1 bits morphed into an RD
RG is nothing like an RGV really, quite different bikes, like the LC and RZs.
The RG was the first production alloy framed bike and Id build a yamagama if i had that choice, but missing parts suck with these bikes in Canada i bet, not long ago RGs were 500buck clunkers in Aus, now theyve appreciated....

Re: R1 bits morphed into an RD
Thx for the interesting info Jon - I believe its an RG (Gamma). Wasn't thinking Yamagamma - more RD hybrid. The Suzuki is not registered which is another hurtle on restoring it plus the parts issue. I'm guessing the R1 conversion vs a Yamagamma may possibly involve the same amount time to monkey wrench but R1 bits are plentyful. I note the article refers to the YVPS upgrade - suspect an RD motor would be no different. Hmm. So many varibles on the Yamagamma option here to ponder - plus I will have to get rid of an RD to make space. Wasn't planning on that. I will ck' out Stan Stephens Yammagamma builds - might find some encouragement there.
