Questions for anyone running Mrrpm Maverick heads on a 1000atv.

Hi,

I’m curious if there is anyone out there running mrrpm maverick heads and his drop in cams on a 1000atv?

What kind of numbers are you making with this combo?

Any issues with the heads? Are they quality pieces?

These heads/drop in cams/and larger TB would appear to be the standard hot rod go fast goodies with larger valves/better flow. However, I would like to go with a proven combo, so would like to hear anyone’s experience.

What the heck just happened?

Hi everyone,

I’m stumped and could really use some advice.

Today I installed a new solenoid and new fuse in my 86 TRX200SX. It worked GREAT! All lights worked, electric start worked, neutral and reverse on the handlebars worked….

Took it for a little spin. All of a sudden it sounded like the starter was stuck…it kept firing like it was trying to start…although it was already running.

I had to disconnect the battery to get it to stop. Then I connected the battery, checked the fuse (it’s fine) and now electric start doesn’t work. I have no neutral/reverse lights, no headlight and no tail light. What in the heck happened? And how to do I fix it? I was so stoked to have it working…and now this. 🙁 I’d really appreciate any advice you can lend…all I can think of is the regulator? Or am I way off base?

Thanks!
Annie

So you want a gear reduction, XP bikes

https://intl.polarisdealers.com/Virt…Chapter_06.pdf

OEM PDF you can print out or reference.
Since no one has posted about doing this, I decided to give it a try on my 850, should be the same for any 550/850/1k bikes. These parts are used in diesel rangers and the highlifter 850/1k

I have had no trans issues to date, but wanted lower gearing.
I’m in the process of installing the parts, not quite done as our set of snap ring pliers just crapped out. Also waiting for a new trans to engine gasket.

Ranger gears and chain part numbers are posted in the pic, also a Turner Cycle reverse chain upgrade was installed.

Special tools-A number torx drivers are used and listed in the pdf 25 and 27 I think, 2 sizes of snap ring pliers are needed as well as a bearing puller for the bearings on the shafts in the trans.

I went the long way and pulled the trans, but now having it apart It could be done quicker in frame.
The pdf instructions are pretty good and I’ll take some more pics before putting it back together.

’86 TRX200SX Electrical Problem?

Hi everybody,

I installed a new fuse and new starter solenoid today. Everything worked absolutely perfect! Lights worked, neutral and reverse lights worked…and then….
A loud noise, like the starter had started itself…and wouldn’t turn off. I finally had to disconnect the battery to get it to stop.

I reconnected the battery, checked the new fuse (which is fine) but the electric start will not work…and I have no headlight, taillight, no neutral and reverse lights.

What the heck just happened? I was soooo stoked to have it working! 🙁

Polaris 500 Runaway – now won’t start

Howdy,
I am new, and this is the first post for me. I’m really glad I found this forum. I bought a 2013 500 EFI used, and it’s functioned well for many typical ranch tasks like towing fallen trees, hauling firewood, etc. I had an interesting problem occur with this over Memorial Day. My wife had driven the kids around in it and said it had backfired when she decelerated fast. I had never heard it do this. It sat about an hour and then she got back in with the neighbor’s wife and her son and started it in park, then shifted it into low. It was idling a little too low roughly and she pumped the gas pedal to keep it from stalling and it hung the acceleration at speed and took off like a runaway horse and as she passed screaming I can’t stop it, she had both feet on the brake with wheels turned fully, and it still pushed straight ahead toward the fence and main road down below. My neighbor and I ran out to help and I shouted turn off the key! My neighbor’s wife turned it off and it stopped about 6′ from a fence that would have put them over a cliff had she gone through it. It was a pretty wild and scary situation. Now, it won’t start but It turns over. It had a battery icon show up, so I charged the battery overnight. It cranks but acts like the injector is not putting in fuel. I attached a photo the girls took of my neighbor and I trying to understand how this occurred after the event. We ended up pushing it back into the shop since it would not start. I would appreciate anyone’s help or input on this. Thanks.
