[CRH]

ok. thats me relagated then?? :\ .....thort we was on to something with the diaphrams?...right ? this may or mabe not? ...but i recently swapped my end can from std to a harpoon carbon oval!!!, now although the sound it made was very impresive? on the road it wasnt so good?....low revs fine!!...but just couldnt get it to rev above 7500 without it holding back? as if i wasnt getting any fuel?...so just to double check? ..i reverted bk to std and it was perfect? only took it to 11000 but that was good enuf for me!!so i thort to myself ime not going to lett it beat me ,i loved the sound of the harpoon so much?.... so i decided to make a baffle for it!!,just to see if a littie bit of back pressure would help??...and guess what?....bingo!! nows revs has it should and goes like a rocket??? ....so ?

[red98]

thats interesting  ......see what happens tommrow.......iam running out of ideas now,will try ade tip about the sliders and then re-check everything ive done so far.....thanks for you help on this one 

[red98]

[CRH]

thats ok! sorry havnt been any help so far?.....its getting to me as well?...dont you just hate it ,when you think you.v don everything?..and it still no good!!!.....i was just like you with my f1 honda that time?...thats why i was sure i was on to sumat with the diaphrams???....

[red98]

iam sure its something simple and something i`ve already looked at...i just cant see anything wrong.....the test rides ive been doing have been on the motorway (when its quite ) and i now have a square rear tyre,its getting low anyway so will be buying some new tyres this weekend.....seams strange buying new tyres when the things not running right but iam not going to give up  :\

[red98]

[red98]

used bike for work today after fitting new down tubes and can.....no change  :\ .....looks like carbs off again,not too sure what iam going to do with them though :rolleyes

[CRH]

would it  be worthwhile sorting a set of carbs complete with tps off net? possibly off a lower mileage bike?...or even someone like hills motorcycle salvage?....had loads of stuff of them?...breaking hundreds of bikes weekly!!....not bad on prices either?

:o :o :o  ah yes......i made a big mistake there  :o :o :o .....with the seconhand carbs i bought to try and trace the problem,i should have fitted them straight to the bike instead of removing the diaphram covers and float bowls for inspection and then breaking the petrol supply t-peice which made the carbs un-useable..hence  swapping the internals over,i might have a problem with the carb boddies !!,supprised no ones said anything yet,you must be all to polite ......i might source another set of carbs and try again,seen a cheap set on ebay close to home and i can always re-sell afterwards
not used hills before,where are they based....off to hemel hempstead today,40mile round trip which will give me plenty of time to test the bike and try and work out whats going on   

[CRH]

[red98]

thanks for that clive  used the bike for work today,approx 50 miles round trip and the bike seams to be getting better,if i ease the throttle open instead of snapping it open the stutter is not there  ...its only when i realy hammer it  that it starts playing up...i think i`ll use it for a while and see what happens,its been a long winter and its just been sat in the garage so parhaps it just needs to be used 

[CRH]

up early this morning,no work so off on the bike,out on the a40 to oxford and on towards whitney ,pull over at hein gerreck (not spelt like that but you know what i mean)closed but had tea in car park,tea break over and down to goring on thames and then pangbourne quick stop and a stretch and then onto reading,henley.marlow and home to high wycombe....thats what i call a sunday morning  ....bike is running better but not perfect,if i ease the throttle open keeping up with engine speed i can aviod the 5000 stutter.its only when i give it full throttle and let the engine catch up that i get the stutter....going to use it for work all this week and clock up a few miles and see if it helps.....managed to round off the square rear tyre  ...forgot to order the new ones  :o

[CRH]
