Quote from: rideitfast on March 03, 2024, 12:14:39 PMAnybody want to guess who made these? They came off a 1975 RD350 and they have been on the bike since the late 70's.


I think they are DGs.

I have dealt with him. He will get back to you, sometimes it takes a while.

Rebuild it with new seals if needed. Easy to do and the rebuild kit is available from Economy Cycle.
I second the motion. HVC sells the kits too. It's a good chance to make sure everything is set up correctly, so that your ratio is good.

I third that, keep the pump. No reason to get rid of it in my opinion. I even run one on my TZ/LC motored TZ replica. On a street bike you will never notice the performance gain or loss, but you will really appreciate the pump when you're at the pump.

I've seen this motorcycle. When Warren lived in Arkansas and I went to visit and meet him for the first time. This is/was just one of the many very cool motorcycles he had at the time.

I do this as well, but no sealant.

I don't

Quote from: gargantua350 on December 07, 2023, 09:47:50 AMHello All,

I have an early rd350 motor and I am going to upgrade to 7 plate clutch.  The thrust washer shows 2 different part numbers on the breakout manual.  Is ok to go with either or?  It looks like the 278 part number is the washer with the bevel.  I was able to source a clutch hub and basket and all the steel plates.  I have new friction plates and springs.  Has anybody used the 278 part in a 7 plate clutch upgrade?

thanks



Do you have the pressure plate and bolts for a 7 plate? Pretty sure you will need those as well.

Quote from: JR on December 04, 2023, 11:17:35 AMSo, one of the rd400 engines that I have came all apart when I purchased a complete rd400 barn find with that extra engine. The parts are all there, but the crank has a bad rod bearing. Assuming that the crank needs rebuilt,
If 110mm rods are used instead of 115mm rods, could we then use the OW31 top end without a spacer?

The 400 crank still has a different stroke regardless of rod length. Why not use the R5 bottom end? I'm sure the 400 bottom end could be made to work with the correct spacer plate, porting changes, etc, but why? It works perfectly on an air cooled 350 bottom end. It works even better on an LC bottom end because then you have the built in water pump you don't have to think about.

I'd go water cooled. I'd take your R5 cases and put one of your RD400 transmissions in it and then I'd port the shit out of that OW31 cylinder you mentioned, get some giant carbs like I mentioned before and have some pipes built that give you the power delivery you need for drag racing. The reason I'd use the R5 cases is because that TZ cylinder will bolt right on and no rod or stroke change is needed and no spacer plate needed. Blaster reed cages fit the TZ cylinders perfectly.

I'd use the motor I have but only more heavily ported with 40 or 42 lectrons or a heavily built banshee motor at the max bore size and still be under the class limit, also with giant carbs.

I have a TZ/RDLC motor in one of my street bikes and I love it. Runs awesome and makes really good power. If you are looking for power though I'd bet Teazer is right about using an RZ or Banshee motor, but in my mind there's just something about the "TZ" part of it that's just really cool.
