To much compression- hard to start

[tazman7]

We have a 1989-1991 Yamaha Warrior. (not sure of year)

And we had it sent out about 10 years ago to Mickey Dunlops four stroke tech to be bored out to a 440. Well anyways this thing has so much compression that you have to hold the electric start, then rope it at the same time.

I am going in for shoulder surgery next week(just kidding but feels like I need it)

Is there some kind of high torque starter that we could put on this thing? We have the biggest battery you can fit in the compartment for it, I think it has like 195 cold crank amps...

idk, with that many amps it should be able to fire it up. check your startor and other electrical components.

Yeah we checked and cleaned all of the wires, still no good. It has been like that since we the engine work done, it has just been in storage and we finally pulled it out a month ago.

try buying some misc electrica stuff off eaby.. I bet u can pick up a newer starter motor ( still stock) and a solonoid (sp) for cheep.


ur starter may have just craped the bed..



also, is the batery old? because if a batery stits for any amount of time it can go dead. may want to try a new one.

You can probably take the starter to an automotive starter repair shop, and have it rewound for more power.

I know exactly whay you mean about hard to start.. my wimpy 300ex starter barely turns over my 330 11:1 let alone anything higher compression than that.

Yeah the battery is only 2 weeks old. I might try taking the starter out and getting it rewound- I cant imagine that being too much $$$

I ran into the same problem when I built my first 440@12:1. It drew so many amps that the cables got hot . It had a problem starting cold because of the cam I put in it. I used a piece of cable from radio shack. Its what you use for cable in high wattage car/truck sound amps.I can get you a pic if you want. It looked trick when it I first set the machine up.

First, make sure it's really the starter. It's possible for even a "new" battery to be bad.

The Warrior is a 12V system, right? Measure it with a multi-meter just to be sure. If it's 12V, then jump start it with a running car (don't worry, the car won't overpower it or burn anything up). The running car should be about 14 volts, and plenty of juice to crank your starter.

If it starts fine by jumpstarting it with your car, your problem might actually be with your battery and not with your starter.

couldent u also run the positive jumper cable directly to the starter,, to elimenate any wiring/ corosion that may be bad.

i put a new set of brushes in my 300ex starter and that made a huge difference.:)

push start it :)

[tazman7]

thanks for all of your help, looks like I have some work to do now.


Push start it---haha, thats how I have been starting it, except I dont push, I pull it with a 4x4 fourwheeler- damn Yamahas being so heavy. Ill stick with my 250r!!:cool:
