Ok so I just got my first rig finally got a go devil longtail with a 23hp vanguard. Ran the pis out of it today and just feel like I can get the motor to perform a lot better than it does. Thinking about a new throttle lever don't like how the stock one sticks. And then air filter and exhaust . What's everyone's thoughts? And what's everyone's thoughts on carbs? I know it's a longtail and there not known for speed but I definitely think it could be improved. Not looking to spend a fortune either just curious what my options are what's everyone think?

Long tails are slow and mods are a waste, if you wana go fast sell it and get a surface drive. If you want to get into some hard to reach places keep your long tail and enjoy the extra time on the water a LT affords you

If it's a used Motor you just picked up, make sure your prop isn't worn down.

Mods on a 23 longtail , I did them on my swomp from backwater . The carb I used is a 34 mm mikuni round slide . You will need additional pieces for a carb swap ( intake , governer lock etc )I suggest using the bps lever to get full travel for the mikuni the exhaust I used is a bps crossover , but you can gut your stocker to save cash . My heads are decked forty thousands . The heads were done by setx. . The cam I installed is a pvt cam. You are not going to run 30 mph . You can achieve a respectable 24-25 if you spend the money . The stock prop I ran on my motor stock was a 9x6 . I'm turning a 9x 8 now running 24 + in deep water. I'm in the process of fine tuning my mikuni , larger pilot jet and smaller main jet. . I bought all these items off of Mmt from members looking to sell them . So it can be done at a price much less than buying all new. You won't have a speed demon capable of running at the front of the pack with modded surface drives, you will have a rig that will ride with the stock rigs and still go anywhere. .

I gotcha thanks for the reply and I'm not expecting a speed demon by any means just thing there's more power there I'm not getting. Is the Bps exhaust worth it does it increase performance at all?

Exhaust alone won't boost performance but its the first step in a 3 step process of getting the engine breathing right.

I gotcha and I'm guessing the 3 stage process is air filter exhaust and carb? Also who makes a better exhaust BPS or Hopkins? And what about messing with the governor I don't think the previous owner did anything to the motor other than service.

I'd leave it stock except heads. Get heads reworked, put a free flow air filter and what ever exhaust u want. As Flint said, longtail isn't for speed! Built to get in places others can't go

Ya that's kinda what I was leaning towards just doing exhaust and air filter not even doing heads and just calling it done

Ok I wasn't sure the kid I bought it from said it would do 22 with him and his dog but he was a younger kid and a lot smaller than me. I thought about upgrading to a surface drive one day but I was really impressed with some of the places this thing got me on Sunday. Places I don't think an airboat could have gone no joke

That kid was more than likely telling you a story.
