Morley’s Muscle Jet Kit! One of the best kits on the market today. Please visit the feedback tab to see what the customers are saying. We developed this kit a number of years ago in the quest to make the best OVERALL jet kit available for the average vmax guy and not only were we able to achieve that but in many cases our kit makes more power everywhere and is even comparable in power to the more expensive aftermarket carbs.
95% of most kits make over 120+ rwhp while still maintaining 38-42+ MPG. More mid-range with same top end as stage seven (in many cases more power then stage seven). Flatslides kill economy for a minimal gain in HP (and in some cases we still outperform the flatslides!).

We have had a few bikes dyno into the 130’s with this kit. The typical bike will make mid 120’s.>>>>>>>>>>>>>>>>>>>>>>>>>

We have three bikes so far with our new jet kit and a fourth that we were short some parts that didn’t get a chance to get finished (it is now finished and runs very well).

First bike is a 2000. It has the quieter Hindle (super sport?) exhaust system and is otherwise stock internally. He was able to tune his bike to 121 HP with our new kit. He is using Factory Pro Titanium needles in place of the OEM needles the base kit includes. The v-boost is being used in conjunction with a t-boost unit. His bike runs well and clean through the entire rpm. He has struggled for a long time to get his bike to this point. I believe his bike started at around 110HP in stock form.

Second Bike is a 1994. When we received this bike it had Hindle slip on’s on it and was a relative dog. We were not able to get a dyno in that form though. Currently it has a Kerker header with a two-brothers carbon fiber muffler made for a TLR 1000. We adapted this muffler (and will be offering this service) recently and would be about equivalent to the 2″ standard Kerker muffler. With our tuning we were able to get his bike to 123 HP 80.5 Torque and it is running great. He is getting 40 mpg including some long high speed test runs that probably killed a mile or two off of it. *****Update – You can see this bike in action in many pictures and a few videos. I have ran a best of 11.05 @ 120 mph with this bike on the stock tire and suspension*****

Third bike is a 1999. It was received with a stage seven installed per instructions and Kerker header with comp baffle. The bike dynoed a very respectable 124 HP as received but with a simple jet change (leaner) jumped to a very nice 127.27 HP and 80.6 Torque. We went a bit leaner on Saturday and got the fuel curve nearly perfect (in our opinion) except a very touch rich in the mid (1/2 clip maybe). Power dropped to 125.8 HP and 79.4 torque. With this baseline we decided to swap to our kit. We completely removed the stage seven and installed out kit. The new dyno showed 125.03 HP and 81.87 Torque. A 2 HP loss in top power but 1 lb torque increase BUT there was an almost 10lb increase in torque in the midrange. However, the test in not 100% valid as the other tests had the v-boost on full time where our kit had it functioning normally. The best part was i got 44 mpg with the new kit and it runs great. We did retest this bike the next year after we added the crankcase breather and was able to get the bike back in the 127rwhp range so it was now stronger with our jet kit then the stage seven. *****Update – I ran this bike at the track and with a Kosman 17″ wheel and front end strapped down I was able to run a 10.97 @ 121 with it*****

The “deluxe kit” will run about $240 but will not have any core needed (or save some with your core which is preferred). It will include a new airbox lid with new flat K&N filter already installed. It will include 4 jets of each size from 155 – 165 (six sizes – 155, 157.5, 160, 162.5, 165, and 177.5 for the PAJ2 if needed) which will give a very nice range to select from. We will try our best to help you get close (tell you what combo’s are currently working) with your jet size to start with. It will also include new springs and air correctors as well as the proper bit to drill out your slides. It will NOT include new needles. Adjustable needles are optional ($50 at kit purchase) but so far the kit is working very well with the stock needles for most people. There is also a new vent breather hose and adapter included in the kit. I can offer this in a true braided setup but they can get expensive quickly ($60 Option).

For a less expensive kit you can deduct $20 for sending me your old airbox lid (you would get a used one back too). So you can get this kit down to $220 if you send your old lid. Don’t forget to add some shipping ($20 in U.S.) to the price too.
This kit is not normally recommend slip-on or stock type headers as they are really choking the flow down. A full header is best for this and the brand doesn’t really make all that much difference. Look for future dyno testing of many different kit and header combinations all on the same bike. The only true way to know what does and doesn’t work!
