I have a 1988 trailboss and the engine has to rev pretty high for the clutch to engage. Does the new 4-stroke bikes do the same thing, Are they as bad or do they just go when you hit the throttle?

 

it sounds like you have a pretty high engagement. the 800 stock is around 1400 rpm and my 450 is around 1800.

 

Sounds high and like someone has done some work in there. Or the other scenario is that it is a 19 year old machine with some wore out parts. Doc

 

I was told this was normal for the old 2-stroke bikes. I have never riden the new sportsmans but they sound like they run at a pretty high rpm compared to a manual shift machine is this true?

 

that is not true. mine run about 6200 rpm. most of them whether it be standard or auto will run pretty much the same top end depending onthe engine. chances are he said the clutch is most likely wore out of the old 88'.

 

Im not talking about top end im just talking about keeping the thing rolling.

 

like i said mine engages at 1450 stock and it idles at 1150 so as you see there isnt much throttle needed to keep it going. if your machine has to be kept reved to keep it going then you either have a high engagement spring and differnt weights or the clutch is junk. i would take it apart if your going to keep it to see what the deal is and let us know.

 

How long have you had it? Has it always been like this, or is this a recent development?

 

I have had it only about 6 months and not riden it except in the yard just playing. I only have about $250 in the thing. Every one I talk to who has had one like it said it was normal. A dealer told me it was normal since it was a 2- stroke it had to rev to to where its power was. I also riden one years ago and it was the same way. Once again I have never riden the new 4-strokes but It just seems they are running high rpms weather they are moving fast or slow unlike a manual shift machine.

 

let me ask you this, does it have an reverse override and if so do you have to push it in to back up. meaning does it start cutting out before you start moving? on my trail blazer(same engine you have) when the stock spring was in it would take off right around (guessing)1800 rpms. you shouldnt have to push thethrottle very far to get it to move. it will rev right up there w.o.t but that parts normal.
