Adjusting valves is not hard, but it's quite labor intensive since the chain tensioner is not easily accessible. Turboflash put a bug in my ear about trying to develop a solution which potentially eliminates the need to access chain tensioner. With Yamaha's exit, the existing sleds will...

Been working on repair flanges for the 11-18 headers. These are made of SS and fit inside the header once you cut the old flange off. These are an interference fit and can be tapped in with a mallet. I opted to install on ID of pipe to minimize chance of leak. Once header is bolted in and the...

Been working on some marginal wheel kits as some skids have areas prone to heavier wear. The kit will work with 2.75" wheels or 4.25" wheels. In addition I have it designed so it will work in areas of rail with large cut outs so it should be a very versatile kit that works in may spots on the...

Been working at these sway bars and soon have some prototype samples ready to ship. For those wanting stiffer I have some with a thicker mid section and I also made some out of different materials. Hoping to get these out at discounted prices for testing/feedback. Product like this really needs...

The OEM heat shield on mid pipe is starting to become a more frequent failure as they age. For what it is the OEM one is a bit pricey at around $220 list and they don't seem to hold up very long even when new. Been working on a better quality one in the offseason. Finally got my cardboard...

A customer/vendor that uses the Yamaha engines in another application has developed a new water pump impeller. After oem failed in 10 hrs on his Turbo 998, he tried an aftermarket one only to have it fail within 2 hrs. This design uses a billet impeller like others but with fewer vanes for less...

I've often wandered how many 50th apex sleds were made. This will surely be a collectible and it would be fun to know how many there even are. If owners could post up the mfg date and last 4 digits of the vin we can probably get a good idea of how many there are. As the thread builds I will...

Been getting requests for the header heat shields. With age they seem to crack and come apart. Yamaha updated them on newer models, but they seem quite pricey. Pretty sure I can offer better quality at a lower price, but just curious as to how many have had issues with them failing.

With a few reported leaky gaskets lately yesterday I decided to test a gasket from current stock just to see if there was any noticeable issues. I did not change suppliers but that doesn't mean material integrity may not have changed. Had no issues during my testing and put 50psi of pressure to...

Starting in 22, driveshaft was rumored to be improved. My 22 did not appear to be, and I have seen at least one 22 shaft that was eaten up by bearing. The 23's have a new part number and all the 14-22 shafts appear to supersede to the new number. These updated -10 shafts were in stock so I had...

5k miles. C/A skis. Excellent 129 track with studs. TD power trail 270 ecu and quiet muffler. Yamaha 4th wheel kit. Has the fox ski shocks with rebound. Motor kit is pending. Sled hit dead center. All arms and shocks are good. Lower frame is good. Bulkhead is dented in center but still...

With the 22 shaft supposedly being hardened I have concern that the driveshaft expander will not work. My 22 is finally in and I'm hoping to get it next week and start testing. Deep down I've always wanted a solution that will work on a worn shaft as well so I have a whole new concept that I'm...

New for this season is a plastic delete 4th wheel spacer kit for the 19+ sleds with 1" axle. This kit adds a 4th wheel to the axle and also eliminates all the plastic spacers on the rear axle. The billet outside spacers fully encapsulate the track tension adjuster bolts to reduce stress on the...

I have a few new upgrade components for the 14-18 models that have the 1/2" rail slot. First off are the nut holders for the tensioner bolt. I now have a billet replacement for these which is better quality than the cast piece. Next up is the axle holders. These pieces are prone to failure as...

I get a lot of people that ask me what the easiest method is to determine if the drive shaft has been spinning so I wanted to share my findings. I find that removing the brake rotor and inspecting the backside of the hub is the quickest way to determine if you have an issue. If the shaft has...

Does anyone have any info on how to identify Viper ECU's? I appears cat prints the same generic 0630-295 part number on all ECU's. It is my understanding sleds with 8 tooth drivers such as XTX and MTX have different calibration for speedometer vs 9 tooth ltx and rtx models. I have an xtx sled...

Ironically the upper idler wheel bearings have a tighter tolerance fit up than the driveshaft and makes removing them somewhat of a pain. The Cat wheel puller is pricey so I've designed a puller that only requires drilling 2 holes in the idler wheel. It works very well and I will have some made...

Trying to find specs on the belt size to see if I can find some aftermarket replacements and it appears they are different sized belts on blast and venom. Country cat shows part number 0823-683 and with dimensions of 43.37 x 1.21". Yamaha does not list length but shows a width of 34.5mm which...

So it has been brought to my attention that Precision EFI has now released a driveshaft saver. It's disturbing to see this lack of ethical value from another vendor. If they really wanted to be able to take care of their customers on the issue I would have gladly offered them dealer pricing like...

Anyone with iQS shock package have trouble getting the button to activate the shock mode? My 21 SRX will not not activate the shock mode. Dealer said the switch likely bad but switches are on backorder. I press button right in the center, but it just toggles through the intake temp, coolant...
