MY 120 made 126 hp and tq, put 20,000 miles in it ran great this NUMBERS that they post are all inflated messing with the dyno. so yes they can be ridden across country, look at some other builds these guys are high on their numbers to sell product that's it SO END OF STORY YOU CAN RIDE THEM

 

These motors are built to be ridden; for touring bikes not barhoppers. We've built over 100 M8 engines over 135Hp, and quite a few years of big Twin cams making similar output, guys ride these bikes all over the country. Some considerations are our M8 124 & 128 kits have less cylinder pressure than the stock M8 engine, and less dynamic compression than many Stage II & III combinations. It is however important to note that higher performance engines require the proper supportive components, they require additional maintenance, they are going to be more fuel sensitive than a stock engine, and the tune is paramount. In the end you need to answer the question on the combination that best suits your needs, a 140 or 150Hp engine may not the best fit for every rider.

 

 

Thanks Jamie, logical and concise answer. Makes perfect sense.

 

Let's pop this to the top , I need a refresher course.
Peace.

 

Today i going to instal 124 big bore from the FM. Hope the quality is perfect .... any way is not way back.... will see

 

I don't think any of there stuff is done in house I could be wrong. I know heads are done by someone else with fuel moto's name to them.

 

It depends on what you consider "any of there stuff" and which element is most important. For example no we don't have a foundry to cast cylinders, we don't grind cams, and yes we have several shops that do production CNC work for our port specs. What we do in house is the development work for each engine kit and the many elements that go into them, and we have long lasting relationships with the manufacturers that supply us; some of them even use our designs for some of their own products. We buy the bikes and we build and test to figure out what works. We offer turn key engine building & dyno tuning, we also have a fairly well equipped machine & fab shop in house as well which runs non stop (this will be expanded upon significantly next month when we move info our new facility). Most importantly we have a full staff that supports sales, technical support, & tuning with a huge emphasis on customer service. If you are from the Milwaukee, WI area you are only an hour and a half from us, I would welcome you to drive or ride up sometime.

 

 

We finished the build 124 set. Configured through Power Vision. Previously, the cam was S & S 465 and decided to leave it for this kit. Of course not exist graphics. But I feel that the moment is higher than 3000 rpm and I do not like it. Heads did ported. The kit is maximum. Which cam would you advise? I want the maximum moment in the range of 2000-3000
Thank!
