    Motor rebuild.. need some advice

    I will be rebuilding the motor on my 2010 BR this winter and im wanting to get some more pulling power out of it. It is completely bone stock right now with 9500 miles and im going through oil pretty good. I already know im gonna put new valves , piston , timing chain etc. What brand piston and valves should I go with? Stay with stock or aftermarket? I was thinking stock valves and aftermarket piston. What you guys think?

    Honda dealership. Unless you're looking for aftermarket stuff. In that case you might want to search for Rincon aftermarket parts. I'm sure someone will correct me but I'm pretty sure BR/Pioneer/Rincon share the same power plant.

    Re: Motor rebuild.. need some advice

    Ive been doing more research and looking at part numbers between the BR and rincon. The piston rings valves all have the same part number so I might be going that route looking for a piston anyhow. The cams have a different part number. There must be some sort of difference in them. Im gonna see if I cant find a mudbuster cam to gain some low end.

    Re: Motor rebuild.. need some advice

    I'm kinda surprised you'd be using oil at 9500 mile. All else OK with the motor? I'm hoping to go well past 20,000 miles before needing any major power train work. Of course not all machine are equal I know.

    Yep everything else is ok except a couple knuckle bushings. Im at almost a quart a week now. Maybe 100 miles. There is no oil leaks and you can only see smoke if its under a load pulling something. You can deffinatly smell it if you are behind it.

    Re: Motor rebuild.. need some advice

    Hi Rexx,
    1. What environment and conditions do you run your BR in?
    2. What air intake mods do you have (if any)?
    3. Do you know how many hours (via Hour Meter) it took to get 9,500 mi?
    4. How often did you change the oil & filter?

    1. I use my BR mostly to deliver firewood in my campgrounds and and trail work at our park
    2. no intake mods have been done. Uni air filter gets swapped out every 2 weeks with a clean one
    3. it has 1655 hours on it
    4. Oil and filter gets changed every 100 hours with Honda oil

    Re: Motor rebuild.. need some advice

    Hi Rexx,
    So is it dry and dusty where you are or humid/damp most of the time?
    An engine leakdown test would be a sure way to tell what has worn and is causing oil consumption.
    A simple compression test might not tell if the valves or rings are the issue, just that compression is low.
    If you are having to or choosing to change the air filter every 2 weeks, then you might consider several of the mods (search these forums for "Snorkle", "Snorkel", etc) to relocate the air intake pipe to fresher and cleaner air.
    New rings, piston, valve seals and a valve job (engine overhaul) will likely fix oil consumption issues.
    A quick thought would be to confirm that the Emissions Systems (PCV & EGR, if it has these) are functioning properly and not clogged/restricted (no check engine light on the dash or codes in the computer).
    I believe the Rincon has the same engine as the MUV-700.
    The trans in the MUV uses a lower 1st gear than the Rincon for better towing/low speed power.

    Welcome to the forum, hope this all helps...kind regards

    Re: Motor rebuild.. need some advice

    It is dry and dusty most of the time. Thats why i change my filter for a clean one on a regular basis. I have been thinking of the snorkel tube that goes up the roll cage. I thought about a compression test but at this time it might be kinda pointless. If i let it sit and idle for about 5 min you can see the snow under the exhaust has oil residue. I already know right now that ill be replaceing valves , piston , rings , cam chain. Probly valve guides too while i have it apart. Im gonna check the cam out once i get in there to see how that is. I have been searching for a different cam for more low end but i can not seem to find one. There is no check lights on at all and as far as the pcv & egr , i dont know if it has these on it.

    Re: Motor rebuild.. need some advice

    I would check the valves and guides before replacing.
    A valve job and new seals would be all that should be needed (with the rebuild).
    Hard to imagine wear to valves and guides so bad that they need replacing.
    (Again, have them checked)
    Cam chain and tensioner, I agree.
    Also, as cheap as it is...put a new thermostat and gasket in it.
    Several here have mentioned a Pre-air filter to further provide clean air to the engine.
    I will change fluids and do maintenance once duck season is over on my BR.

    Re: Motor rebuild.. need some advice

    I will be tearing into it right after new years and ordering parts. Once I get into it ill post up some pics. Any idea if a Rincon mudbuster cam would work in the BR?

    Re: Motor rebuild.. need some advice

    I do not know on the MudBuster.
    I do know that a few here have installed Big Bore Kits (BBK).
    Bigger piston, cylinder, cam, etc as part of a package (kit).
    Changing something like the stock cam with a performance part, often requires custom tuning and additional parts to "see/feel" the benefits.
    I wonder if any here might comment about using a Power Commander V (5) or similar fuel tuning device, instead of doing a cam swap?

    Re: Motor rebuild.. need some advice

    I have been checking out that power commander and it might be all I need for a little bit more pulling/towing power. Its a little pricy but for a few more pounds of torque im sure its worth it.

    I'd steer clear of different cams, this is a fuel injected engine thats tuned to the installed cam. the mudbuster cams are better for older carborated rincon engines.
    A BBK is an awesome way to go, but i have read on various rincon build ups about premature failure using them. i personally wouldn't be affraid of them, just noting what i've read.
    OK so the PC-V is the bada$$ upgrade i always suggest, but you have to do a performance muffler to really get a benefit from it. but with that comes a louder exhaust. so it's give and take.... but the extra power is awesome. also you could write your own fuel map that adjusts for air density at higher elevations. anyway.... they work awesome but the performance mufflers are quite loud.

    Re: Motor rebuild.. need some advice

    All parts are ordered for the rebuild. Piston , rings , all valves , cam chain & tensioner , gasket kit , and a few bushings that are needed. I just went with all oem products from Honda. Im gonna hold off the PC-V till spring when the cash flow is better. Where is a good place to order a new intake ( snorkel ) from ?
