scubajohn Posted April 9, 2004 Share Posted April 9, 2004 Well the first problem with my bike it has started to surge when at about 4.5K and up in rpms. While accelerating. It does not go Waaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa it goes WaaWaaWAAAWaaaaWaaa You can hear it and feel it. Could it be the power comander ? I have had it on the bike for over 8K with no problems till now. I have never ran a FI cleaner should I try that ? will clogged injectors make it surge ? I am going to try removing the PCII and see if that helps or at least make sure its not loose. Any other Ideas ? While I am at it when you change sprockets Whats the best way to tell when its time to replace a chain ? I am in the replace area of the swing arm but it went into that when I lost a tooth up front. thanks Quote Link to comment Share on other sites More sharing options...
Chester Posted April 9, 2004 Share Posted April 9, 2004 The chain could also be the problem. Spin the wheel and see if there is a real tight and loose spot in the chain. If there is, it could cause the bike to surge. Quote Link to comment Share on other sites More sharing options...
scubajohn Posted April 9, 2004 Author Share Posted April 9, 2004 Will do the chain has about 16K I thought they went like 20-25K miles. But I do have a heavy right hand when it comes to taking off Quote Link to comment Share on other sites More sharing options...
Animal Mother Posted April 10, 2004 Share Posted April 10, 2004 Hi John: I dont know how often you ride your bike, but I had a very similar problem with mine. It turned out to be my battery :roll: So obvious yet so far away I jump started it to take it for a ride and only cruised through town initiall at very low RPM's, maybe up to 3-3.5k. Well, this wasnt enough to sustain a charge on the battery from the alternator, so she started surging, lights went on and off, FI light came on, then finally died on my way back. Tried to turn key and dead as a door nail :cry: Prob. not it, but thought I would add my dos centavos Steve Quote Link to comment Share on other sites More sharing options...
scubajohn Posted April 10, 2004 Author Share Posted April 10, 2004 it could be I think its still the original battery from 2000. and when at idle if I rev it a little the light will get way brighter but if at over 1K ior so and I give it gass it does not. More things to look at now if I just had time. I ride it as much as possible, It had sat about 4-6 months while I was moving but now gets ridden at least 3 times a week for a 30 minute freeway trip to work and then back. I try to keep it under 100 but ususaly cruise at about 90. Thanks keep them coming. Quote Link to comment Share on other sites More sharing options...
EVLXX Posted April 11, 2004 Share Posted April 11, 2004 What year is it? Have you checked the fuel pressure yet? Quote Link to comment Share on other sites More sharing options...
tweety Posted April 11, 2004 Share Posted April 11, 2004 i've noticed a similar RrrrRrrrRrrrRrrr feel when above 5000 rpm on my bike. current known problems on my bike are a dead R/R and a very loose chain past the end of its life. I didn't notice the problem when doing the charging voltage test (revved rpms to 5000 while in neutral.) so I wouldn't be surprised if the chain is part of the problem...

scubajohn Posted April 12, 2004 Author Share Posted April 12, 2004 Well took the PC II off and it may have gotten a little better but I think its just wish full thinking. I guess its time to buy a chain. Quote Link to comment Share on other sites More sharing options...
scubajohn Posted April 12, 2004 Author Share Posted April 12, 2004 I have not checked fule pressure and dont have a clue how to but if the chain does not help then I will dig deeper Thanks for all the info Quote Link to comment Share on other sites More sharing options...
tweety Posted April 20, 2004 Share Posted April 20, 2004 *bump* Did you resolve this yet, John? Quote Link to comment Share on other sites More sharing options...
scubajohn Posted April 20, 2004 Author Share Posted April 20, 2004 nope I have not had the time to get a new chain and I am fairly sure now that the pc2 is off it is the chain. I tried to tighten it and then less than 100 miles its back to out of spec Quote Link to comment Share on other sites More sharing options...
scubajohn Posted April 24, 2004 Author Share Posted April 24, 2004 New chain and the pc2 back in and all the surging is gone!!!!!!!!!!!!! at least I know how to tell when my chain is shot now hehehe thanks again Quote Link to comment Share on other sites More sharing options...
tweety Posted April 24, 2004 Share Posted April 24, 2004 Sweet, thanks for the update. I guess I should get my old, extremely loose chain done sooner rather than later!... :oops: Quote Link to comment Share on other sites More sharing options...
