How do I know if my bike is ready for a rebuild?

I would recommend a leak down test first. If it has more then 12% leak down, it's time to look into it.

I wouldn't recommend going over 30 hours on pistons and 60 hours on crankshaft and bearings.

If your engine timer has over 80 hours on it, you're way past due.

How hard is it to ship an engine or suspension to C4MX?

Not hard at all. Go to Wal-Mart and purchase an ice chest big enough to put an engine in, they are around $25.00 and it comes with wheels and a handle.

Wrap engine up well in cardboard so it doesn't move inside the ice chest. Tape the outside of the ice chest up well so it doesn't open up during shipping.

For Suspension, purchase a hard plastic gun case from www.walmart.com for around $50.00. I don't recommend using the gun cases available at Wal-Mart stores, they are less expensive, but break easily.

Use a shipping service like UPS or FEDEX. Insurance is your responsibility.

What is the turn around time?

It depends on what work needs to be performed. Head porting usually has a 1 or 2 day turn around. If copper seats are installed, it's around 2 weeks. Complete engine mod are around 2 weeks. If it's a busy time of year, it may take longer, so get your bike or engine in as early as possible.

Why should I go with C4MX instead of the other engine modification companies?

-Because you get a 1 on 1 relationship with the person that builds your engine, you can call us anytime that you have an issue with gearing, jetting, suspension setup, etc...

 

-We've dyno and track tested our products back-to-back against the most popular modification companies and have proven our engine packages to be superior.

 

-We only use parts that make a difference in performance and reliability. We're not trying to sell you muffler bearings.

Can I run pump gas?

It depends on how much compression you want. If you're going with the high-compression piston, valves and gaskets, you need to run a high quality race gas such as Renegade Fuel. I have Renegade Fuel available for purchase.

 

Just a piston, pump gas is fine.

How often do I need to rebuild my engine once it's modified by C4MX?

The following is a basic guideline, your individual needs may vary:

15 hours: Pull head off, inspected everything and put in new rings.

30 hours: Install new piston and rings, valve springs, inspected everything.

45 hours: Pull head off, inspected everything and put in new rings.

60 hours: Install new cranks and all bottom-end bearings, new piston and rings. Install new cylinder and valves if necessary.
