The thing I admired about Guzzi for years was the engine layout and character. That was the whole attraction to me. That's what made Guzzi different from all the rest. The first time I saw one on tv was one of the dirty harry movies towards the end. I don't remember which one but I do remember...
Got them in and checked them with the meter
cruise rpm 92
revved 104 db
Compared to my original open db killers
cruise rpm. 94 db
revved 108 db
I think they still have plenty of flow and am happy with the result. Would they have been louder if I had made them shorter like...
Food for thought...I am not a sound engineer nor am I a air flow engineer. You notice I made them longer than oem length. I can still cut and weld them shorter to oem length but wanted to experiment.
The muffler construction and anything you add like db killers are affecting 2 very different...
I wound up ordering the California 1400 db killers. They were too big to fit in my Mistrals but once cut they did slip over the ones I had and I was able to use them after all. Once installed I will check with my decibel meter the difference and post the results
I was able to repurpose one of...
The local shop is doing a big bore and cam on a V9. I think they are having a cam made. When I stop in I will ask. Stock the engine is understressed and should run a long time without stressing any other components. I knew I was getting 55hp when I bought it. The Audace with a handlebar change...
I think 400-600 lb bikes is where the sales are. I find myself riding my 900 lb touring bike less and less and really seriously considered replacing it with a 1250RT. Neither one of my sons want to ride my touring bike or even borrow it for a trip.
I dis google it but could not find the actual Mistral oem db killers. Just other aftermarket alternatives. If someone has a pic of the oem ones I could probably reconfigure mine as I know some excellent welders who could weld up whatever I make. You have probably figured out I like to make...
The V9 roamer I bought came with Mistral long mufflers. After reading about how some have db killers installed I looked at mine and there they were. I removed them to look at them and I bet they have been cut. I will post a couple of pics and maybe someone else that has them can say.
So is 80x74 for the V7 and
84x77 for the V9 correct?
Is the V85tt and this new motor for the V7 also 84x77?
An oversquare engine explains the rev's and I see from your explaination where they got the power.
What is the bore and stroke of the 820cc kit you offer for the V7?
The most noticeable difference from the previous-gen V9 engine is an increase in horsepower; our V85 TT Adventure produced 66.3 peak rear-wheel horsepower at 7,900 rpm and 48.6 lb-ft of torque at 5,300 on the Jett Tuning dyno, compared with 51.3 horsepower and 47.3 lb-ft of torque from the 853cc...
The whole attraction of the roamer for me was it resembled the standard style bikes of late 70's early 80's I remember. I looked at the CB1100 and the Z900RS and was leaning towards the Z900RS until I remembered what I don't like about inline 4's. The vibration/buzziness.
So now I was back to a...
I admire creativity. Thats cool that you make things like that. It's cool that if you can't buy it for a specific bike, no problem, you just make what you need.
I bought the V9 roamer to make it my own. I like seeing other peoples solutions and ideas.
