CJ750 motorcycles are rare birds in the US or in any other country, even in China nowadays. The mechanical engineers who know how to fix this kind of old school bikes either died or retired.

How many times do you encounter that no shop in town will take your bike for service when you ask them for help? There are reasons for that, because these shop's engineer do not know the old bike well: they may see the SV engine only a couple times in their life time. They think your CJ750 M1 or CJ750 M1M motorcycle should not run at all because they have never seen engines with such low compression like yours in a live engine, but you know your CJ750 just runs great even when 3 adults hop on her.

For those of you who have the spare money in you pockets and no time for your bike except time to ride her, there are some motorcycle shops out there can help you out:
- Your local BMW dealer's shop: they know how to work on the "air head" and "oil head".
- Your local Ural dealer's shop: Ural is similar with your CJ750 motorcycle.
- Your local body shop for regular body work and paint.
- Your local motorcycle paint shop for your custom paint job.

Hello my name is Dan. I have been a motorcycle mechanic since 1967. I run a one man motorcycle shop in the wilds of north Idaho, near Cataldo. In summer I work on motorcycles. In winter I do Taxidermy. I built this site to help all motorcyclists world wide, aiming it toward the do it yourself Motorcyclist.

Working on any engine is always dangerous therefore..."ANY RISK REAL OR IMPLIED FROM USING THIS INFORMATION IS STRICTLY THE RESPONSIBILITY OF THE USER."

Over the years I have learned a few things about engine repair that can be applied to almost any engine. Most of this stuff I learned in the school of hard knocks, that is, I broke things... sometimes expensive things, and guess who had to pay for those things! So click on links, read on and enjoy.... and maybe save a little money !

Hi, below is the Online Motorcycle Repair Course. Now, I'm not going to claim that this course will train you as well as a formal Motorcycle school. But then again it is FREE. Which is more than I can say for several, State run, EXPENSIVE Junior College's I know of. To top it off, guys I've talked to, who have taken these courses, tell me the courses were no good. If you do pay for formal instruction, make sure you see the job placement record for the graduates of whatever school you go to, before you give them any money.

I will try to take you from knowing nothing about Motorcycle Repair to being able repair your own and others Motorcycles. How much you learn and how well you repair your motorcycle will depend on you. Remember what the Bible tells us... " And whatsoever ye do, do it heartily, as to the lord, and not unto men;" (Colossians 3:23) In other words always do your very best. In reality, you are really working for God, and not man.
