Here's a typical 4- stroke top end service. When the head is off I strip it down and inspect the valve train. I can actually see the face of the valve, the valve seat and measure the valve springs. If all looks good, I then v***r blast the head and clean out all the carbon build up. Install new valves stem seals and re-install valve train. Piston/ rings, gaskets, spark plug, coolant, oil/ filter and the timing chain/ tensioner also get replaced.

This 2020 300XC came in for some loving and a TSP upgrade. Performed the standard top end service with wossner parts. Stripped down the cylinder and v***r blasted everything. The powervalve had some pretty serious carbon build up. Along with the top end I performed some maintenance items. I cleaned both fuel injectors, replaced the inline fuel filter along with the micro- filter, installed new crankcase pressure sensor with an updated brass bracket and replaced the oil pump. We installed a TSP medium compression head and a ECU reflash with the ERM module. The TSP kit is the best upgrade you can buy.

Here we go again. The cost of parts will be significantly higher very soon. This is parts of the email I received this morning regarding cost on parts.

-every oil company has told us they will be increasing prices starting in May. We expect to see a 10% and will also be hit with shipping surcharges.

-Not only are the products made by petroleum going to increase, but we will see increases on all shipping containers as well.

-Do not forget that there is a new tariff of 25% on finished products made from steel and aluminum as well.

Unfortunately, the new 25% tariff on products made from steel and aluminum is 95% of our dirt bike parts.

Good news. The new shop is not far from the old shop. 5 minutes away. I was able to stay in the littleton area. It is a smaller shop, but. We can make it work. I will not have a ton of room to store bikes, so we will all need to pickup fairly quickly when the bike are finished up. I get the keys next Wednesday and I'll start moving in. Should not take too long to get all set up.

New address is
190 W. Rafferty Gardens Ave #6

Hopefully this gets out to as many of my customers as possible. It has come time to move locations. I have been in this location for 10 years, and it's been good to me. But, time for a change. I would love to stay in the littleton area, but....... There is not too many options down here. Possibly looking at shop right in the middle of town. I76 and I25 area. I will keep everybody updated on new shop location. I just wanted to throw it out there. I would love to stay in this area, but. I don't know if that's possible. Big wheelies everybody and keep an eye out for further posts from me.

This is a 2022 300xcw with 81 hours. Small amount of metal transfer on the cylinder walls, but. I was able to clean it up with muratic acid and hone. The power valve had a ton of carbon build up. I completely strip down the cylinder, v***r blast the cylinder and all the power valve components, then reinstall with new orings and seals.
I always ultrasonic clean the fuel injectors and perform a back flush to insure the engine is not running lean due to plugged up injectors.
Some other key maintenance items I strongly recommend at the same time, is. Replacing the inline fuel filter on the fuel pump assembly, the micro fuel filter in the connector and the crankcase pressure sensor.
Even though the oil pumps can last a very long time, I do strongly recommend installing a new one with every top end. It's a small price to pay for good insurance knowing the oil pump is new. If the oil pump stops working, you won't know until it's too late and usually by then. Extreme engine damage is very likely.
This is the correct way to perform a top end replacement, along with performing the other maintenance items, this will help insure your bike is in tip top condition to keep you on the trails.
I will only install the highest quality parts available for your bike. No cheap parts will be going into your engine.

They have arrived. Finally got my order of the upgraded crankcase pressure sensor bracket/ holder for the TBI bikes. The stock bracket sucks and they leak all the time. Inexpensive upgrade for the CCPS and don't forget to replace the sensor every time you do a top end.
