    Anyone ever replaced an engine on a ztr with a different size shaft than the old engine. How hard is it to get the right size pulley's and clutch?

    :blob3: nope, i always replace as close to the orig. as possible, much easier and basically bolts together in an hour or so. pulleys and a new clutch can be another $3-400. tony.

    Thanks Tony, I'm sure that is the way to go, however this engine is approximately $800 less than an exact swap. It's a 25hp Kohler, just the shaft is 1 1/4 instead of 1 1/8, it may also be 1/2" longer also. I'm just wondering if it's possible to find the pulleys and clutch in the larger size.

    i did it was not too bad. i bought the new clutch for $170.00 and the pulley was about $10.00 and my shaft was a half inch longer too. i just used a half inch spacer to compensate for the difference. but the wiring plug on my new engine was different then the old engine. so i just took it to my local shop and had them rewire it which cost like $75.00.

    Here's the next question, Is a 25 hp kohler that is not a v twin a bad engine? Is the v twin worth an additional $800 or $900? It's a twin cyl it just doesn't say v twin in the specs.
