shambles1980 Posted January 7, 2013 Posted January 7, 2013 ok back with what is turninmg out to be a little money pit of a rxs 100. you may remember that i recently found a bunch of mis sized bolt holding the reed and inlet to the barrel of my bike.. well there was a reason for that.. All the threads are knackerd. and the one on the top left.. Seems some bright spark snapped a bolt in that, then went ahead and tried to drill it out and destroyed part of the casing so if you screwed the bolt in you can see 50% of it (the right hand side) so theres no way thats going to work. Also they didnt manage to get the sheered off bolt out any way.. i could use an extractor. and use a full length bolt that would then give me atleast 20% of the length of the bolt holding, which would probably hold. But, i have seen a head and barrel for sale. But it would need a rebore.. Now im in gwynedd (north wales) and i want to know if any one arround me here is able to do the rebore. (form 0.5 to 0.75 or 1.00) and whilst they were at it could they port it too (may as well do 2 things at once) the porting is not essential. but i would need a rebore, the barrel isnt gouged or scored its just worn, so a +.25 would do, (from +0.50 to +0.75) but as they can go up + 2.0 Id be happy with going up 0.50 to a total of +1.0.. which should guarantee no defects. and would probably take the bike up to a true 100CC instead of the 98 or 99 they come out of the factory as. ok i am rambeling. any way that was the question i had, and whilst im at it does any one know the correct price for a service like this would be? comments like (rebore should be about £xxxx, and porting should be about £xxxx. and if you did both at the same time the total cost should be something like £xxxx) would be welcome. just so i know if im getting ripped off or not. I could take it to a local engeneering company and see if they could rebore it, but id rather find a specialist that wont say "that'l do"
blackhat250 Posted January 7, 2013 Posted January 7, 2013 Aye shambles " a local firm did my DT400 , for £40, i supplied the piston, there are firms out thereGrampian engineering [ liverpool] Racoon [ london] they will port and supply pistons,,Also road an dirt performace, Bradford,, £27 per cylinder,,
Moderator drewpy Posted January 7, 2013 Moderator Posted January 7, 2013 I've used western rebores on Oldham road a few years ago. Not sure they are still there but loads of experience as its a 2nd generation owner.
shambles1980 Posted January 7, 2013 Author Posted January 7, 2013 i may give these guys a go then.. " http://www.pjme.co.uk/acatalog/News.html " as reccomended by dirtydt seems a reasonable price plan for rebor + port tidy.. im going to strip the whole thing down whilst the cylinder is away. gotten to the point where i think i found all the little leaks that caused it to be low on power. all around the head and barrel, but as i got everything to do the bearings and seals il do that when its away. No reason not to without the barrel as i cant piss about with it without those crutial parts.
Moderator Cynic Posted January 8, 2013 Moderator Posted January 8, 2013 Very reasonable. The challenge is getting them to answer the phone... Very busy i think.
Moderator DirtyDT Posted January 8, 2013 Moderator Posted January 8, 2013 Remember to take any studs, reed block and anything else off. Send a piece of paper in the box saying what you need doing and anything you expect to be included such as top end bearing and circlips.
shambles1980 Posted January 8, 2013 Author Posted January 8, 2013 i went ahead and sent them an email.. "i think i may phone tomorrow lol" i wanted to know if i need to supply the piston + rings, as they state theyd prefer to supply them but i cant see any in stock for my bike. i also wanted to know if they needed the head, i dont know if the want to do anything to the combustion chamber too, (i need to add the bike has only done about 125-126k miles..) all the damage done to it was done by the previous owner. "well the one previous to that" and it is all down to heavy handed wrench usage.. Bolts snaped.. threads destroyed. some idiot trying to drill things out ruining the casing.. All of which could have been avoided. so its really quite annoying/dissapointing. Hopefully this last purchace will have the bike better than new. i have been pretty horrified so far with all the little things that have been wrong with the actual engine, and i have considerd just replacing it as it would probably end up cheaper. if its still a blowing air sucking cant produce enough power piece of crap after this il just see about getting a replacement. im sure there must be a good engine stuck to a bent/snapped frame some where. it just seems they all get striped to component parts. hopefully the new barrel will do the trick though. for a free bike this thing has been pretty expensive so far. and im still to tackel the wiering. replace bulbs new indecator lens and respray. But its a 2 stroke. and one of the better 100cc's so it will be worth it. and who knows i may be able to break the 70mph mark without much difficulty with the new barrel (but i really doubt that lol) oh.. will i need to change the jets after i get the rebore? im pretty sure just changing to reeed valves should be enough, but it never hurts to ask. and im changing to a pod air filter so im probably going to end up running pretty lean if i dont jet up?
Moderator Cynic Posted January 8, 2013 Moderator Posted January 8, 2013 I cant get hold of them either. Pods are not good. Really plays havoc with inlet reasonance and such. They are also bloody loud pn a stroker. Not tempted with a dt125lc motor. Even a dt175. That should fit quite neatly with only a little swearing....
Moderator mervin Posted January 8, 2013 Moderator Posted January 8, 2013 metal ended pods are worst, all foam is better and on a pipe to move em back from the carb helps,
shambles1980 Posted January 8, 2013 Author Posted January 8, 2013 id like a lc motor but i dont know where id stick the rad.. "well i know where lol, it wouldnt be going on the handle bars.. just cant see how to jam one on there without to much work"
Moderator Cynic Posted January 8, 2013 Moderator Posted January 8, 2013 What about the 175 then. Save the exhaust that would be close to a straight swap.
shambles1980 Posted January 8, 2013 Author Posted January 8, 2013 id imagine a 175 may be cheaper due to learners not allowed to have them, and being a bit low of an upgrade from 125 for the people who want to go up a notch or 2.. i will have a look, hope i can just salvage the original engine, but keeping my options open
blackhat250 Posted January 8, 2013 Posted January 8, 2013 Go for a YZ125 engine,,, peaky fast motor,,,
shambles1980 Posted January 9, 2013 Author Posted January 9, 2013 stinky ebay bidders sniped my barrel when i was in the crapper.. sent some emails off to bike breakers now.
shambles1980 Posted January 10, 2013 Author Posted January 10, 2013 whats the deal then do i have to actually phone breakers yards or something because they dont seem to answer emails .. could really do with abbeymotorcycles replying to me but they dont seem to check emails?
