chrisadams810 Posted November 23, 2017 Author Share Posted November 23, 2017 Looks like I'm missing the shim from the advance mechanism Which is odd... Does anybody know the dimensions of the shim? Link to comment Share on other sites More sharing options...

chrisadams810 Posted November 23, 2017 Author Share Posted November 23, 2017 There's a shim on the Newtronics diagram but none present on the actual bike. I thought this might be fishy. Newtronics claim it is on the bike already. Link to comment Share on other sites More sharing options...
Moderator drewpy Posted November 23, 2017 Moderator Share Posted November 23, 2017 just checked the Newtronics pdf and doesn't say there's a shim there, just an exloded diagram. I'd fit it and check the rotor clears the timing triggers before commiting to starting Link to comment Share on other sites More sharing options...
chrisadams810 Posted November 24, 2017 Author Share Posted November 24, 2017 I tried posting the diagram that I have last night. It shows a shim. The rotor won't clear the triggers. I turned the engine with a spanner and it broke the locating legs on the rotor. Link to comment Share on other sites More sharing options...

Yes i saw the shim but it didn't say that was part of the kit or not. its def not OEM. basically use a penny washer to pack it out so it clears Link to comment Share on other sites More sharing options...
chrisadams810 Posted November 25, 2017 Author Share Posted November 25, 2017 Newtronics claim it is part of the motorcycle but state it's so thin that it won't make a difference in the operation. I beg to differ. In hindsight I wish I'd bought the Pamco kit. It looks more robust. But I'll have to work with what I've got. I'm hoping they'll send me a replacement rotor.

chrisadams810 Posted December 19, 2017 Author Share Posted December 19, 2017 Hello again, Promise one day I'll post something selfless and useful. So I'm still waiting on this replacement part from Newtronics. It's in the post they say. I'll give them the benefit of the doubt. It's allowed me to ponder something. When setting the timing on the crank for timing on the points. The notch on the cam for your advance timing mechanism should be parallel to the ground shouldn't it (9 o clock)? My notch is sitting at 10 o clock. And I know the crank is set right at R/F Is it possible the cam sprocket is out a tooth? Link to comment Share on other sites More sharing options...

Lf = left fire ie ignition Lt = left timing ie cam Link to comment Share on other sites More sharing options...
chrisadams810 Posted January 26, 2018 Author Share Posted January 26, 2018 So today I decided to make a ride to work the bikes maiden voyage. I made it but not without problems. The bike will top out at 60mph. Is this normal? And the bike cuts out at idle. Link to comment Share on other sites More sharing options...

Tommy xs Posted January 26, 2018 Share Posted January 26, 2018 Well I bought the xs400 dohc more than twice the mpg of the rd and only fractionally slower, never had any trouble keeping up anyway, will do a constant 80+ on the motorway and still going strong 36 years later, but must admit when I see the prices of Rd's now I realize I fucked up big time 1 Link to comment Share on other sites More sharing options...

And the bike cuts out at idle. could be timimg, check with strobe light. carbs could be blocked in the tiny galleries in there. should be getting 80 mph tops so its not too far away. run some fuel cleaner through, even using the bike will loosen it up a bit so it may be just that.

chrisadams810 Posted January 27, 2018 Author Share Posted January 27, 2018 Timings been checked with strobe. I'm happy with that. Carbs have been stripped. Jets look a little worn but I imagine that'll allow more fuel in. I guess it could be giving it to rich a mixture. Might purchase a jet kit. I am now running fine filters which won't help matters. Any recommendations? Link to comment Share on other sites More sharing options...

Had the same hp as a dt175 (17). you have the 16v 400, that's 45hp. Tdr is little more than that but weighs nowt. Not wanting to rub salt in......... well..... just realised reading TDR forum that my bike being unrestored original(ish) is prob worth around 4k now. Ropey ones are up for 2 and a half. That got you a minter 2 years ago. 1 Link to comment Share on other sites More sharing options...
