BlownCorona Posted November 18, 2013 Share Posted November 18, 2013 the block isnt alloy so it wont shine up like that without a shit load of work plus its rough for a reason, if you polish the fins super smooth, it wont cool properly as the roughness gets in the airflow and helps transfer the heat, so id vote paint it black too Quote Link to comment Share on other sites More sharing options...
ODB Posted November 18, 2013 Author Share Posted November 18, 2013 Tonights wee job: Should contrast nicely with the head when the gaskets finally arrive and its farken back together! Quote Link to comment Share on other sites More sharing options...
ODB Posted November 21, 2013 Author Share Posted November 21, 2013 back together Initial warm up run was had pootling around for 15 mins below half throttle. Seemed to run ok, if not hugely peppier than before. Will go for a harder run again tomorrow and then a full on run and see what happens. 1 Quote Link to comment Share on other sites More sharing options...
Rookie Posted November 21, 2013 Share Posted November 21, 2013 You should have ridden up a hill as soon as it fired. Quote Link to comment Share on other sites More sharing options...
ODB Posted November 21, 2013 Author Share Posted November 21, 2013 Did a bit of reading/net research mainly on 2 stroke dirtbike forums and concensus seemed to have a few runs, letting them go cold in between times, gradually going harder. Oh well Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted November 22, 2013 Share Posted November 22, 2013 If there's any issues you can just give bore quick hone to roughen it again then do as rookie suggests. goal is to wear in rings before bore gets smooth Quote Link to comment Share on other sites More sharing options...
Rookie Posted November 22, 2013 Share Posted November 22, 2013 Yea this^. You don't have to thrash it, just make sure it is loaded up, you can do the tempering after the rings are bedded in. Quote Link to comment Share on other sites More sharing options...
ODB Posted November 22, 2013 Author Share Posted November 22, 2013 I also noticed that it was making a bit of a whistling noise last night. Is this normal post refreshing the top end? Quote Link to comment Share on other sites More sharing options...
Rookie Posted November 22, 2013 Share Posted November 22, 2013 What sort of whistling noise? Out of the side of the head? Quote Link to comment Share on other sites More sharing options...

ODB Posted August 13, 2014 Author Share Posted August 13, 2014 this cunty thing hasnt ran for ages. Winter / sports / another sprog have seen it stashed and not looked at for ages but got some more motivation lately - bought some new bars cos as cool as the Z bars were they were fucking dangerous when tucked for max speed haha. Had a couple of near death experiences! another angle Down to 7/8" too so makes shit cheaper than 1" fucken harley tax Plans are now to chop rear a bit and find a plastic legshield - suzuki FR50 seems the most likely fit as cant find a true V50 one anywhere.

ODB Posted March 11, 2015 Author Share Posted March 11, 2015 Ok bike is back and seems to be running / starting well - when cold. After its been running for a while and gets hot it seems to bog down and stall. I need to let it cool down and then will run again. Thoughts? Initial thoughts could be running a little lean / soft seizing? So run some oil in fuel also? Carb jetting?? Perhaps gear oil needs changing although that seems sweet?

MKD Posted March 11, 2015 Share Posted March 11, 2015 lean, semi to way lean. my fr50s doing that now too. my needle is on the bottom clip and still needs more gas. larger jets when i get round to it. mines the same starting when hot too, won't most of the time. is yours dying when its running hard or just when it warms up? plug colour? mines dry light brown as it is now, needs to go richer with bigger jets to get browner drop the clip to start with before doing jets Quote Link to comment Share on other sites More sharing options...
Benno Posted March 11, 2015 Share Posted March 11, 2015 Yeah, sounds like it's lean to me. Try a plug chop, run it up to decent revs then kill the ignition so it dies without idling. Does it run better with the choke on? 2 Quote Link to comment Share on other sites More sharing options...
